Abstract: In the solar cell system electricity did not be produced if there was no dye because there would be no electron flow in the conduction band, where the dye on the surface of the thin layer of TiO2 acted as an electron injector in the conduction band. The number of dyes adsorbed on TiO2 was influenced by several factors, including dye concentration, immersion time during the adsorption process, and thickness of the TiO2 layer. The performance of DSSC was studied by measuring currents with voltage variations. The best conditions for the dye adsorption process of mangosteen peel extract on TiO2 semiconductors were obtained at a concentration of 25%, immersion time of 120 minutes, and thickness of TiO2 of 5 times of coating. The best efficiency was also obtained at a concentration of 25%, immersion time 120 minutes, and thickness of TiO2 of 5 times coating.

Abstract: As rubber comes in contact with various surfaces, wear characteristics are critical to predicting ultimate performance of the end product. Abrasion testing can be used to predict overall durability of the material as it may perform in applications. The Rotator Drum Abrasion (Din Abrasion) method measures the volume loss due to the abrasive action of rubbing a test piece over a specified grade of abrasive sheet. The result can be reported as a relative volume loss or an abrasion resistance index.

Abstract: The aspiration of current study is to address the Magneto Hydro Dymaics (MHD) radiative flow of an incompressible steady flow of Jeffrey nanofluid explored using CNT (single and multi walled carbon nanotubes) over a stretched /shrinking surface. Heat and mass transfer characteristics are accounted for in the presence of joule heating and thermo-phoretic effects along with viscous dissipation. The governing non-linear partial differential equations are reduced to non-linear ordinary differential equations by using some adequate dimensionless variables and then solved numerically with Runge-Kutta method. The optimal solution expression of velocity, temperature, and concentration are explored through spatial representations by using several values of physical constraints with contour plot and surface plots. Further the coefficient of skin friction and local Nusselt number are examined through graphs. Artificial neural network introduced at this juncture to obtain the predictive values of engineering constraints from physical constraints.

Abstract: The large number of tofu industries spread in many cities in Indonesia produces a lot of liquid and solid waste. Tofu industrial wastewater is known to contain high COD so it must be processed before being disposed of into the environment. This research studies the reduction of tofu liquid waste COD and uses it as a power plant using the Microbial Fuel Cell (MFC) system. In addition, MFC technology is combined with developing spirulina at the cathode. The results showed that electricity amounted to 171.44mW.m-2 for 1 electrode and 171.44mW.m-2 for 2 electrodes. The percentage of reduction in COD of tofu liquid waste reached 40% and OD of spirulina biomass reached 0.5.

Abstract: A Hopfield neural network transfers information with feed-back connections. These are similar to magnetic materials where stability of the bit storage plays a crucial role in exchanging strength through the spin(+1 or -1) orientations. More stability helps in storage of multilevel data such as image data. A Complex Valued Hopfield Neural Network (CHNN) with a multi-stable Hopfield model has low stability in two-dimensional phase. Rotor Hopfield Neural Network (RHNN) added to CHNN increases its stability in multidimensional phase. Hyperbolic Hopfield Neural Network (HHNN) is an extension of CHNN by Clifford algebra. In our proposing system, we are extending the theories of stability between HHNN and RHNN by investigating this process through the projection rule. HHNN is independent of the resolution factor and there is a gradual increase in the noise tolerance. Thus, it is comparatively more stable than RHNN.

Abstract: In this study an attempt has been made to investigate the applicability of BTTT to mustard oils obtained from different parts of India and thereby examine the influence of geographical variations on BTTT. In the present work, the mustard oils of different brands used for analysis, such as Kacchi ghani mustard oil (Kgmu, Dalda), Kacchi ghani mustard oil (Kgmu1, Mahakosh), Kacchi ghani mustard oil (Kgmu3, Dhara), premium kacchi ghaani mustard oil (Pmukg, RRO Mustdil) and refined mustard oil (Rmu, Dhara) exhibited BTT in the range of 19 to 21.0 0C. The result have demonstrated the reproducibility through the analyzed data. Hence It is observed that mustard oil fulfils BTTT values as per Regulation (Food Products and Standards) 2011 of Food Safety Standards and Act 2006. The coefficient of variation is in between 0.24-0.43 in case of BTT. BTT values prescribed for the certain vegetable oils comes under the mandatory food laws in some countries but due to development towards hybridization in oil seeds, reconsideration in laws is required.

Abstract: In the present research study, four different groundnut varieties such as T-64, Tg-37A, TRG-4 (Trg-4) and Karad4-11(K4-11) were grown under different geographical places in India. The proximate analysis, oil yield and physicochemical properties of collected groundnut seeds and their extracted oils were determined for their nutritional assay. It was found that the seeds contained in the range of extracted oil, moisture, crude protein, total ash, crude fat, crude fibre, carbohydrate and calories per 100gms were 39.98-42.12 % (±0.8828), 1.24-2.45 % (± 0.5105),27.5-30 % (± 1.0681),1.77-2.24 %(± 0.2174), 28.8-30.2 % (± 0.6416),1.68-2.35 % (± 0.3211), 34.41-37.76% (± 1.4414) and 519.64-526.96 (± 3.4593) respectively. The specific gravity, viscosities, impurities and refractive index of the extracted groundnut seed oil and colour were in the range of 0.9150-0.9165 (± 0.0007), 91.48-91.58 (± 0.0432), 0.03-0.05(± 0.00851) ,1.4628-1.4636(± 0.0003)and 1.23-2.32 (± 0.5141) respectively. AV (mg KOH/g oil), IV (g I2/100 g oil), SV (mg KOH/ g oil), unsaponifiable matter content (%) and ester value of the extracted oil from groundnut seeds were in the range of 2.78-3.37 (±0.08), 90.24-93.9 (± 1.5478),190.08-192.48 (± 0.9856),0.56-0.62(± 0.0258) and 187.1-189.31(± 0.9667) respectively. This study is empirical and on the basis of finding it is revealed that groundnut seed oil can be a valuable source of edible oil.

Abstract: Reinforced Earth Wall (RE Wall), is a composite material formed by cohesion less soil and flexible metal/geosynthetic reinforcing strips. Construction of a Reinforced Earth wall is straightforward and simple. Merely place a layer of facing panels, bolt on the metal/geosynthetic reinforcing strips then backfill and compact. During the rainy season, it has become common to hear about the failure of RE wall, consequently disrupting the traffic. There are various causes for failure like bowing, bulging and tilting, unfortunately the user of road/highway suffers a lot in terms of inconvenience. This paper analyses the causes of failure, effects and remedy, to minimise and avoid these failures, by keeping suggested remedies during the design, construction and maintenance stage, by implementing good industry practices, during design, construction and maintenance stage

Abstract: This paper presented a Triple Frequency passive array stacked patch antenna, which work on the L-band frequencies of 1.25 GHz, 1.46 GHz and 1.65 GHz. The array contained 16 rectangular stacked patch antenna elements and these 4×4array were fed by independent coaxial method. This design reduced the effects of the complex feeding network on antenna performance and the distance between each antenna element was only half of free space wavelength, so the size of whole array was reduced significantly. This antenna can also be combined into a bigger array with more elements, then make the miniaturization of the array more obvious.

Abstract: In contemporary society, workplaces have become more complex and dynamic because of the strong need to perform sophisticated tasks and use advanced technology. In these situations, trust can be an important factor of "decision aid" in dynamic and uncertain situations when complex systems are impossible to comprehend and when flexible behaviors are necessary to combat unexpected situations that arise, which are unavoidable. Measuring the human trust of a worker interacting with systems is vital in predicting his or her decision-making. This research examined human trust using an Electro Encephalo Gram (EEG) by recording, identifying and analyzing specific brainwaves. This research adopted a word elicitation study from previous research to evoke situations of trust and mistrust and used a power spectrum analysis for the recorded brainwaves. The results identified that while alpha and beta waves were stronger in the trust situations, gamma waves were stronger in the mistrust situations. Therefore, based on the activities of the brain waves associated with trust, we concluded that trust can impact effective decision-making by increasing concentration and performance, which are related to alpha and beta waves. Contrarily, mistrust can interrupt effective decision-making by increasing stress and anxiety, which are related to beta waves.
