PV-generator-battery systems are common for large village loads while PV-battery systems tend to be preferred for smaller village loads. This study compares three power system architectures (PV-battery, PV-generator-battery, generator only) for part-time evening domestic lighting in a small isolated rural village. Although the evening load profile disfavors PV systems, the small load also disfavors generators. Multiple technical and financial figures of merit are used to compare systems. Detailed consideration is given to the relationship between power availability and power cost, a metric uncommon to rural electrification studies. The net present cost of the generator only system and hybrid system is invariant with changes in annual unmet load allowance. The net present cost of the PV-battery system decreases with increases in unmet load-the higher granularity in the installed capacity of PV-battery systems allows reductions in system cost if project stakeholders allow power shortages for evening lighting. This design consideration can reduce the high initial of PV-battery systems. For the domestic lighting load modeled in the study the PV-battery architecture becomes the lowest cost option for an unmet load allowance of 1% or greater.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130388028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A chemical disaster at just one of these facilities could kill or injure thousands of people with acute poisoning [1].” Because of the common proximity between residences and chemical facilities in the United States (U.S.), hazardous chemical detection and early warning systems is vital and frequently missing feature of public safety systems. In many instances, the cost of chemical detection equipment and monitoring systems is prohibitively expensive, preventing concerned citizens from participating in a hazardous chemical detection and early warning system. To address the need for an affordable, distributed, off-the-shelf hazardous chemical detection early warning system, this paper presents a method for designing and prototyping a unique environmental mobile device (EMD) for detecting hazardous chemicals. Employing affordable gas sensors, the EMD measures and communicates hazardous chemical concentrations to an Android smartphone or tablet custom-design app which time stamps and geolocates the measurements. Initial development efforts have focused on recording variability in sound levels, temperature, humidity, carbon monoxide (CO), and nitrogen dioxide (NO2) levels in the outdoor environment. The data logged by the EMD and app is then uploaded to an interactive web-based map that displays both individual and aggregated routing information. Both the smartphone app and web app use a simple color scale (green, yellow, orange, red) to indicate the intensity of the sensor readings at a particular place and time. In the future, the EMD and smartphone app could be used as part of distributed hazardous chemical detection and early warning system that would deliver real-time information and alerts to communities that may be at risk of hazardous chemical exposures.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122238168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although there are existing solutions to overcome this problem, none of them served to be customizable, economical and user friendly all at the same time. Therefore, one of the best options that could be useful for these affected class of people is a gesture-based interaction with their environment, in particular their wheelchairs. The proposed system named as `Gest-BOT', uses a small camera mounted very close to the user's hand, which tracks the small movements of their fingers to understand the direction of movement of the wheelchair. A gesture recognition system which identifies the gesture is then interfaced to the wheelchair control system in order move it to the desired location. Gest-BOT is effortless to use, customizable, economical, highly convenient and nonintrusive. The hardware implementation of Gest-BOT consists of a wheelchair, an Arduino board based ATmega microcontroller and an Intel Atom EBC-352 processor, which uses MATLAB® executables for gesture image processing. We have also calculated the response of the system under various conditions which is detailed in the paper.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"700 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122984110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this approach, spatial domain digital watermarking technique is adapted wherein the patient information is embedded as watermark into the lower order bits of the medical image pixels. The watermark, which comprises of text data, is encrypted to prevent unauthorized access of data. To enhance the robustness of the embedded information, the encrypted watermark is coded by concatenation of Reed Solomon (RS) codes and low density parity check codes (LDPC). However, even under no noise conditions, the extracted watermark accuracy depends on the region of the medical image into which it is embedded. Hence extracted watermark accuracy is evaluated for three different regions of the image with no noise. The bursty wireless channel is simulated by adding impulse noise to the embedded image. Furthermore, turbo channel coding is proposed to correct the transmission errors over impulsive noisy wireless channels. The efficacy of the proposed approach is illustrated with the implementation results on a watermarked medical image.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128452930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The entire world economy is dependent on technology today. Yet, certain remote areas are deprived of this basic amenity, either due to the lack of concern from the authorities or due to the unawareness about harvesting locally available resources. In this paper, the challenges faced by one such area are identified and the issue is solved by utilizing alternate energy source. This paper describes how rural electrification can be implemented in a cost-effective manner without compromising efficiency. The area under study is located farthest from the existing power grid and the high expenditure that has to be incurred in its electrification withdrew the authority from this task. However the project team formed under the Local Integrated Network of Kerala IEEE Students identified that the solar energy can be harvested in the area. All the project parameters were analyzed in detail and thorough research was done on the land and its inhabitants. Underground cables were chosen as the means of transmission. The project implemented provided electricity for basic lighting devices. The project can be viewed from a global perspective, as the characteristics of the area selected are identical to similar non-electrified regions around the world.","PeriodicalId":265555,"journal":{"name":"2012 IEEE Global Humanitarian Technology Conference","volume":"452 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116763866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
