Webpage Portal for Crowd Sourcing on Food Waste Management

Abstract: This paper represents a Web portal for crowd resourcing on food waste management where the leftover food is donated to the needy and to people who lack or suffer from food. The need for donation is due to the wastage of food. In this present scenario, wastage of food is on large quantity in many places like restaurants, weddings, social functions, college canteens, and many other social events. Some people donate food manually by visiting some organizations. In order to reduce the issue of food wastage, there are Web sites that have taken efforts to help people donate food through online mode. This system provides a new approach where leftover food is donated to needy people or organizations, for both governmental and non-governmental people. The system is an effective means of donating food to organizations, orphanages, etc., over the Internet. This has a potential for avoiding the wastage of food. Using the Internet mode for donating food is mainly helpful to the NGO organizations where they can raise the request for food. So, the donors from the hotels and marriages can donate food to the wanted people by seeing the request given on the Web site. It provides information that provides motivation to come up with a successful application, thereby describing existing donation system that works for the betterment of the society. A new donation request will be created on the portal, and once the request is accepted, then the food request from food donor to food receiver is processed and updated on the webpage.

Effect of Mg and Sr Additions on the Microstructure, Mechanical Properties and Reciprocating Wear Characteristics of Hypereutectic Al-14Si Alloy

Abstract: The explorative attempt to harness new materials that could be utilized for manufacturing products with sophisticated geometry for aerospace and automotive applications necessitate the exploitation of Al-Si-Mg alloy family. Al-14Si alloys which posses 1% Mg exhibits a microstructure that contains primary Si particles, eutectic Si and Mg2Si in α-Al matrix. With a view to improve the mechanical properties of this alloy, Sr modification was carried out by adding 0.04% Sr to the molten metal. The Mg2Si phase has high melting temperature, low density, high hardness, low co-efficient of thermal expansion and high elastic modulus. The best results in the microstructure were obtained through a combination of Sr addition and T6 heat treatment which enhances the mechanical properties and wear resistance of the alloy Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

Block-Random Access Memory-Based Digital Pulse Modulator Architecture for DC–DC Converters

Abstract: This paper proposes a new digital pulse-width modulation (DPWM) and digital frequency modulation (DPFM) architecture using block RAM (BRAM) present in the field-programmable gate arrays (FPGAs). In Xilinx FPGAs, Block RAM (BRAM) elements are available only with a synchronous reset. As the synchronous reset is used in this code, the synthesis tool implemented the code in a single BRAM element. This minimizes the decoding logic and reduces the area. Block RAM available in FPGA is used to store the desired pattern to derive the variable duty cycle and variable-frequency pulses. This DPWM/DPFM architecture can be used with switching type of DC–DC converters under both light- and heavy-load conditions. Architecture is developed with Verilog hardware language for three different control bits (4 bit, 5 bit, and 6 bit), synthesized, and implemented with Xilinx PlanAhead 14.2 tool. This proposed architecture provides higher resolution without any requirement for higher clock frequency and larger logic resources which ultimately wits the small change in output voltage produced at the output of power converter. Maximum operating frequency of 306 MHz can be achieved for 4-bit control input. For the 6-bit control input, 4096 different bit patterns are stored to derive the more precise pulses to control the DC–DC converters.

Traffic Impulsive Leeway

Abstract: Traffic congestion is the major consideration in the present traffic control system. Traffic density keeps on increasing day by day therefore new technologies are needed to address this issue. The traffic present in each and every lane should be monitored accordingly and the vehicles should be allowed to control the traffic. An analysis is needed to monitor the traffic and to set the time for each lane and to allow vehicles sequentially without affecting the functionality. But these control systems are not depending on the traffic density, it functions irrespective of the traffic density. In order to foretell the real time traffic jams in the lane, the status of the traffic should be monitored continuously at various time period. With the help of RFID scanner, the emergency vehicles are prioritized and by using graphical user interface the data is collected and loaded on to the server and this helps to identify the emergency vehicle automatically and the traffic light should be adjusted accordingly. This system is helpful for emerging traffic control lanes and it is highly effective.
