Abstract: Mixed-model assembly line has great importance because of its variability. This type of assembly line includes two important problems, the first is the mixed-model line balancing problem and the second is the model sequencing problem. The mixed-model line balancing problem is the problem of assigning tasks to stations in a way to get an effective performance measures, and the model sequencing problem is the problem of deciding the sequence in which different models should be released to the same assembly line. This paper focused on sequencing problem that dependent on the results of balancing problem. There are several methods could be used for solving the sequencing problem, we described the Goal chasing 1 method. This method is applied on the assembly plant of Electronic Industries Company (EIC) that assembles different models of automatic changeover (ACH) which is dependent on the results of (MMSLO) program with a heuristic balancing method.

Keywords: mixed-model assembly line; Goal chasing 1 method; (MMLSO) program; heuristic methods.

Abstract: Although martensitic stainless steel materials are not used in large quantities compared to austenitic and ferritic grades, they play a huge and often unseen part in our modern world due to their combination of strength, toughness and moderate corrosion resistance. However, after wielding the martensitic stainless steel tend to lose their mechanical/micro structural integrity. In this study, the microstructures and mechanical properties of a welded AISI 410 martensitic stainless steel after different heat treatments were studied, with aims to restore the hardness and improve grain refinement of the materials. The results show that the structures of the steel after austenitizing treatment at 1020°C, are of lath martensite mixed with a small amount of retained austenite. Apart from TP2 specimen, where martensite phase was transformed into ferrite structure, the structures of the tempered steel are mixtures of tempered martensite, carbides and reversed austenite dispersed in the martensite matrix. The result indicate that the tempering regimens (500, 600 and 700°C) carried out improved the hardness and grain refinement leading to the existence of finely distributed carbides in the materials. TheTP3 specimen experienced secondary hardening phenomenon, displays the best comprehensive mechanical properties and has the highest hardness value of 370.7 HV close to the parent metal after tempering at 700 °C.

Abstract: Glass fiber reinforced plastic (GFRP) composites are one of the most widely used composite materials, as they have good balance between properties and costs. GFRP laminate composite widely use in aircraft industry to produces the aircraft main bodies, doors, ailerons, spoilers and other aircraft components. During their in-service life, These composite materials can expose to different working condition as well as to different environments, where Moisture can be introduced to the materials; in such working condition the properties of such materials needs to be well understood for appropriate design and use. The focus of this research is to determine the effect of aviation fuel on the glass fiber reinforcement plastic. Therefore, the GFRP specimens were manufacture by vacuum infusion process and the specimens were subjected to aviation fuel immersion tests, using AVGAS 100LL and ATF, in order to study the effects of oil absorption behaviour on flexural properties of GFRP composites. Both solutions affect the flexural properties. However, for tests performed, the ATF promotes the highest effect on the flexural properties.

Abstract: Electronic Intelligence (ELINT) is the result of observing the signals by radar systems to obtain information about their capabilities. ELINT provides timely information about threatening system such as radar that guide aircraft or missile to target. It can be installed in all kinds of airborne, sea based, and ground based assets and is used for identifying and avoiding threats. Amplitude comparison direction finding method is used in this design to determine the Angle of Arrival of the received signals by distributing eight antennas circularly. Determining the direction or Angle of Arrival of a radar signal is fundamental to electronic intelligence. It uses eight directional antennas circularly distributed, whose boresight are pointed in different directions. The boresights are typically offset from each other such that the gain patterns overlap along the 3dB edge. When the signals arrived, it is down converted to intermediate frequency using Digital Down Converter (DDC) and Fast Fourier Transform (FFT) is taken. The ratio of power amplitudes of the antennas are compared to known antenna gain patterns which is then used to calculate the Angle of Arrival. The equation of Angle of Arrival was derived by taking the ratio of signal amplitudes between each two adjacent antennas due to their associated Angle of Arrival over 360 directions. This method makes the system simple in analysis and implementation and gives good accuracy and resolution over a wide range of frequencies. This system provides the horizontal (azimuth) direction of the arrived signal as related to the reference direction automatically without steering antennas and then overcomes the mechanical problems. The proposed system in this paper operates over a wide band of frequency (0.5 to 18GHz) and covers the whole 360 degrees.

Abstract: A series of carbon nano?ber (CNF)/ polydimethylsiloxane (PDMS)-based nanocomposites was prepared using in situ polymerization technique by critical manipulation of factors, such as method of preparation and chemical modi?cation of ?ller. Quanti?cation of the degree of dispersion was done by introducing a dispersion degree parameter. Ceria-based composites are developed as potential electrolytes for intermediate solid oxide fuel cell applications and a better understanding of the ionic conduction mechanism serves this purpose. Ceria based composites were produced by several processing routes using a ceria-based ceramic host (Sm, Gddoped ceria) and various Na and Li carbonates. Simple ceria/carbonate two-phase nanocomposites were synthesized by the carbonate precipitation method followed by a thermal treatment.

Abstract: Cloud Computing is that the new buzz word in today's computing world. though there's large buzz, many of us are confused on specifically what cloud computing is, particularly the term is used to mean nearly anything. Cloud Computing has been visualised because the next generation design of IT Enterprise. It moves the application software and databases to the centralized massive data centres, wherever the management of the data and services might not be absolutely trustworthy. This distinctive paradigm brings concerning several new security challenges, that haven't been well understood. This work studies the problem of ensuring the integrity of data storage in Cloud Computing. Especially, we think about the task of permitting a third party auditor (TPA), on behalf of the cloud client, to verify the integrity of the dynamic data kept within the cloud. To securely introduce an efficient third party auditor (TPA), the subsequent two basic necessities should be met. First, TPA should be able to efficiently audit the cloud data storage without demanding the native copy of data, and introduce no extra on-line burden to the cloud user. Second, the third party auditing method should bring in no new vulnerabilities towards user data privacy. During this paper, we utilize and uniquely combine the general public key primarily based homomorphic authenticator with random masking to realize the privacy-preserving public cloud data auditing system, which meets all above needs. to deal with these issues, our work utilizes the technique of secret key primarily based bilaterally symmetrical key cryptography that enables TPA to perform the auditing without demanding the native copy of user's keep data and therefore severely deduces the transmission and computation overhead as compared to the simple data auditing approaches. The projected system offer safer design by using light weighted APCC (Authentication protocol for cloud computing).In previous system SSL is employed for this purpose. Than challenge handshake authentication protocol is employed for authentication. Challenge handshake authentication protocol is employed for authentication once client request for any data or service on the cloud .We will use VerifyProof run by TPA to audit the proof from the cloud. Initially request sends for identity of client by Service supplier authenticator. For sending or receiving data over cloud we are going to use blowfish for security purpose.

Abstract: Thin films of CdTe have been deposited on to stainless steel and fluorine doped tin oxide (FTO) coated glass substrates from aqueous acidic bath using electro deposition technique. The different preparative parameters, such as deposition time, bath temperature, pH of the bath have been optimized by photo electrochemical (PEC) technique in order to get good quality photosensitive material. The deposited films are annealed at different temperature in presence of air. Annealing temperature is also optimized by photo electrochemical (PEC) technique. The film annealed at 200OC showed more photosensitivity. Different techniques have been used to characterize the as deposited and annealed (at 200OC) CdTe thin film. The X-ray diffraction (XRD) analysis showed the polycrystalline nature and a significant increase in the XRD peak intensities is observed for the CdTe films after annealing. Optical absorption shows the presence of direct transition with band gap energy 1.64 eV and after annealing it decreases to 1.50 eV. Energy dispersive analysis by X-ray (EDAX) study for the as-deposited and annealed films showed nearly stoichiometric compound formation. Scanning electron microscopy (SEM) reveals that spherically shaped grains are more uniformly distributed over the surface of the substrate for the annealed CdTe film. Photovoltaic output characteristics and spectral response of the annealed film have been carried. The fill factor (ff) and power conversion efficiency (?) of the cell are found to be 71 % and 3.89 %.

Keywords: PEC, XRD, band gap, EDAX, fill factor and efficiency.

Abstract: For under water images, denoising and image enhancement is essential. Underwater exploration of the seafloor is used for various scientific reasons such as assessing the biological environment, exploring mineral, and for conducting underwater living organism's analysis. As the images underwater suffers from the different degree of distortion. Underwater images are affected by the light scattering and colour change, so most of times images that we captured are blur. Due to light scattering incident light get reflected and deflected multiple times by particle present in the water which degrade the visibility and contrast of the underwater images. The underwater images have poor image quality. First it uses some pre-processingmethodology which is to be done before wavelet threshold de-nosing. Then it will use webers law for image enhancement along with wavelet transform then we get some adaptive output and the images that we recovered are more enhanced as well as it reduce the noise level.

Keywords: Underwater images, Enhancement, Denoising, and Wavelet transform Webers law.

Abstract: To evaluate the performance of locally made plastic box calorimeter, developed method heat (Q) vs. temperature (T) was used for measurement of specific heat. Specific heat of the three different types of pure polypropylene (pure PP beads, single rolled PP sheets and double rolled PP sheets) and jute fiber reinforced (5%) polypropylene samples were determined. The measured specific heat of samples were showed excellent agreement with the literature value. The mechanical properties like tensile strength, percent elongation at break& young's modulus were measured for corresponding samples. The tensile strength as well as elongation at break was decreased as the rolling number of PP sheets increased but at the same time young's modulus showed increasing trends.

Keywords: Specific heat, single and double rolled PP, tensile strength; elongation at break, young's modulus.

Abstract: We propose in this paper a few information about tracking Greenland icebergs and to avoid accidents for ships and for easy transportation in oceans. An iceberg or ice mountain is a large piece of fresh water ice that has broken off a glacier or an ice shelf and is floating freely in open water, may subsequently become frozen into pack ice (one form of sea ice). As it drifts into shallower waters, it may come into contact with the seabed, a process referred to as seabed gouging by ice. Density of pure ice is about 920 kg/m³, and that of sea water about 1025 kg/m³, typically only one-tenth of the volume of an iceberg is above water (due to Archimedes's Principle). The shape of the underwater portion can be difficult to judge by looking at the portion above the surface. This has led to the expression "tip of the iceberg ", for a problem or difficulty that is only a small manifestation of a larger problem.

Keywords: Icebergs, density, tip of iceberg, Archimedes' principle.

Abstract: Managing production and operations with available resources have become the most challenging job of today's software industry. This involves not only optimizing on available resources but achieving improved productivity with minimum cost of production, controlled overruns and adherence to schedule. The challenge to optimize becomes even more hard-hitting and uncompromising when the requirement changes are too frequent as in case of agile software production system. This dynamic behaviour of agile software production systems can be modelled using system dynamics (SD). The software production process can be modelled and its behaviour predicted along with consequences of managerial policies on the production system. Agile development is one of the solutions to the problem of extremely complicated methods, which is being adopted of late by various software production systems. Hence, the prime objective of this research is to investigate how the application of system dynamics can aid in the performance analysis and improvement of Agile software production systems. The paper puts forth some of the dynamic forces that affect Quality Assurance (QA) activity which are modeled using system dynamics. The feedback loops developed explain how schedule pressure in an ongoing software project, which arises when the project is behind its time schedule, leads to an increased error generation rate. With increasing number of errors committed, a major part of the available resources (man, machine, money etc.) are utilized in error correction and rework instead of development activities. This adversely affects the project's progress rate thereby leading to increase in schedule pressures and adding to greater cost of poor quality.

Abstract: The bark of Dalbergiatrichocapra Baker is traditionally used in Madagascar as an anti-infective remedy. Beyond the recently known anti-quorum sensing (QS) properties of the D. trichocarpabark n-hexane extract, QS-independent anti-infective activities have been also detected. Indeed, chromatographic fractionation allowed the elution of fraction F1 that affects neither bacterial growth nor the expression of QS-related genes (lasB and rhlA) but significantly reduces the formation of biofilm (55.8 ± 2.3%, as compared to control conditions). Moreover,F1 is able to disrupt the structure of one-day old preformed biofilms, which consequently increases the effectiveness of an antibiotic, levofloxacin, on biofilm-encapsulated bacteria (dead bacteria in presence of levofloxacin-F1 were two-fold higher compared to levofloxacin alone). This F1-triggered disruption of biofilm formation is presumably due to an induced reduction in flagellar-dependent motilities (swimming and swarming) as well as in exopolysaccharides production. The inhibitory effect on biofilm appears reversible as the biofilm formation resumes when F1 is discarded from the culture medium. This interesting non-bactericidal mechanism of action may justify the traditional uses of D. trichocarpa in Malagasy medicine. Further work aims at identifying the compound(s) responsible for this biofilm disruption.

Abstract: When a text is accessible in a digital format, it is a task in the field of text mining to accurately predict the sentiment of a text or the intention with which the text was written. In this paper, we are trying to develop a system that will analyse the intention with which a particular text is written. Sentiment analysis becomes a tedious job in the domain of text mining as the problem of polysemy (one word with different meanings) and synonymy (many words with the same meaning) arises frequently. Our intention is to take this process one step ahead by analysing and verifying the sentiment using image processing in order to identify the intention with which a sender is sending a particular text message. By processing the image, it will help to improve the accuracy of sentiment analysis as the facial expression is captured while the sender is sending the message. The facial expression will account for the mood of the sender at that instance which enhances the sentiment analysis. This system will give a report of all the activities of the sender and will eventually detect the mood of the sender just with the help of the messages that he has sent.

Abstract: Reconstruction of large bone defects remains a challenge in the orthopaedic clinic. Genetic modification of biomaterial scaffold provides the opportunity to control the cellular microenvironment by inducing expression of tissue inductive factors to promote angiogenesis and osteogenesis. Angiogenesis in tissue-engineering scaffolds is essential for supplying oxygen and nutrients to the cells, removing waste products, and ultimately functionalizing implanted scaffolds. However, it was difficult to visualize and measure angiogenesis in three-dimensional (3D) scaffolds or new bone in bone tissue engineering in vivo and non-invasively. Photoacoustic microscopy (PAM) is a novel imaging modality that can acquire volumetric data in a non-invasive manner. In this study, we fabricated lentivirus-mediated genetic modification of 3D-PLGA/nHAp scaffold (PH), which can deliver recombinant lentivirus carrying cytokine gene-pdgfb (LV-pdgfb). In vitro, the modified scaffolds (PHp) continuously released bioactive LV-pdgfb particles for up to 5 days, and expressed PDGF-BB and significantly promoted migration of bone marrow-derived MSCs (BMSCs). In vivo, we detected that there were significant increasing of expressing of pdgfb and angiogenesis related genes. In this preliminary study, by using acoustic-resolution PAM (AR-PAM) and optical-resolution PAM (OR-PAM), we have investigated the blood vessels pattern in mouse calvaria in vivo. We have confirmed that PAM is a useful tool in evaluating neovasculature in bone tissue. In the future, we will quantify the neovasculature in 3D-scaffold which assisted bone regeneration by PAM scanning, and correlate the neovasculature with new bone regeneration in a murine calvarial critical bone defect model in the future work.

Abstract: Unstructured data mining has gotten to be topical as of late because of the accessibility of high-dimensional and voluminous computerized substance (known as "Big Data") over the venture range. The Relational Database Management System (RDBMS) have been utilized over the previous decades for substance stockpiling and administration, be that as it may, the constantly developing heterogeneity in today's data requires another capacity approach. Subsequently, the NoSQL database has developed as the favored storeroom these days since the office bolsters unstructured data stockpiling. This makes the need to investigate proficient data mining procedures from such NoSQL frameworks since the accessible devices and systems which are planned for RDBMS are regularly not straightforwardly relevant. In this paper, we concentrated on points and terms mining, in light of bunching, in archive based NoSQL. This is accomplished by adjusting the engineering configuration of an investigation as-an administration system what's more, the proposition of the Viterbi calculation to improve the exactness of the terms order in the framework. The outcomes from the pilot testing of our work show higher exactness in examination to some already proposed procedures, for example, the parallel search.

Abstract: Antenna diversity uses two or more antennas to improve the quality and reliability of a wireless link where there is not a clear line-of-sight (LOS) between transmitter and receiver. Instead the signal is reflected along multiple paths before finally being received. Each of these bounces can introduce phase shifts, time delays, attenuations, and even distortions can destructively interfere with one another at the aperture of the receiving antenna. Antenna diversity is effective at mitigating these multipath situations. This paper investigates the various antenna diversity techniques and combining techniques.

Abstract: Smartphones have become a revolution within the last years. The increase of the computing and communication capacity of these devices allows them to perform a wide range of tasks. Newer PDAs (eg, iPhone, Treo, Palm T/X, HP iPAQ) access the Internet to download files, retrieve information, and update software programs directly on the device without having to connect to a desktop or laptop computer. cellular wireless networks location management is an important mechanism that enables the network to discover the current attachment point of a mobile so as to facilitate successful information delivery.
