Research into WiFi solutions has fallen off as ubiquitous mobile solutions penetrate even the deepest rural communities worldwide. This paper argues that the latest wave of WiFi mesh networks offers benefits that traditional top-down WiFi and mobile networks do not. In addition, we propose ethnographic and participatory methods to aid the effective rollout of mesh inverse infrastructure with and for a given community. This paper describes and then analyzes a mesh for voice rollout within a situated context. We explain how to conduct informed community co-design and how to factor in local socio-political concerns that can impact on the design, rollout and subsequent maintenance of community-based wireless mesh networks. While we have not yet analyzed baseline and initial usage data, we do have new lessons to offer.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122346545","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 success of this alternate business model depends on the solutions for two challenges -- by taking work to people to leverage large educated population in India and making enough work available for the workforce to work and earn. Though solution to the first challenge is implicitly available through increasing penetration of Information and Communication Technologies (ICT) in India, the second challenge requires enough tasks to be available by enabling business organizations to adopt crowdsourcing. Since enterprise tasks are not readily crowdsourcable owing to security, compliance and contractual reasons, this paper proceeds to describe an end to end system which encompasses technical solutions that could help crowdsourcing business tasks, by tactfully overcoming the existing business constraints. For business tasks, we consider Insurance Claim Form Digitization which is one of the most common tasks taken up by outsourcing enterprises.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115129623","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}

These abstractions simplify the creation of sensing applications and provide for a high level of customization and flexibility, thereby enabling a variety of wired and wireless sensors to be connected to mobile devices. To avoid issues with modifying locked consumer devices, the framework's driver architecture is implemented at the user-level. To increase the variety of mobile sensing applications, we have developed a reconfigurable interfacing board that allows the framework to communicate with external sensors that have low-level digital or analog interfaces. We discuss field deployments that leverage the framework to address global health issues.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123388665","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}

There is a gap between the farmers and the knowledge of agricultural experts. ICT can fill the gap between farmers and the experts. In this paper, we have proposed a semantic web based architecture to generate agricultural recommendations, using spatial data and agricultural knowledge bases. Our knowledge base acts as a domain expert and will send recommendations to the farmers based on climate conditions and geographic data. We have shown experimental results as a part of implementation of our proposed architecture. A farmer sends a query to the query engine, in order to get information for a specific crop. Query may be related to GIS data, crop knowledge base or both.

However, People Living with HIV/AIDS (PLHA) tend to socialize less among themselves as well as among others because of stigma [1]. Some PLHA avoid social functions because such functions disturb their ART (Antiretroviral Therapy) schedules. Others avoid it because socialisation often involves expenses. Depression, fear, discrimination, loss of pride and respect are other reasons. Lack of socialisation gives PLHA a feeling of being all alone in the hardest time of their life.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131128083","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}

It is central to the diagnosis and management of lung ailments like asthma, chronic obstructive pulmonary disease, and cystic fibrosis. Spirometry is generally performed in medical clinics using clinical spirometers---devices that measure the instantaneous exhaled flow (liters/sec.). High-end clinical spirometers can cost upwards of $5,000 USD. Portable spirometers generally cost between $1,000-$4,000 USD. Apart from being costly, these devices are not readily available in developing countries. Most developing regions have low cost peak flow meters in prevalence. These devices ($10-$50 USD) only sense a subset of lung function measures and are generally considered inadequate for managing and diagnosing lung ailments [2]. SpiroSmart [1] is a smartphone-based approach that measures many common lung function measures using the phone's built-in microphone. It does not require any additional hardware or adapter to be attached to the phone. The low cost of smartphones as compared to spirometers allows lowering of access barriers to full-fledged lung function measurement in the developing world.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"574 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116300709","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}

Motivated by this situation, we perform a statistical analysis of the run-time delays of express trains in IR. We find that trains in some specific geographical regions, such as the Indo-Gangetic plain, regularly experience high delays, indicating high congestion in these regions. However, rather surprisingly, the amount of traffic alone cannot explain the geographical variation of delays in IR. We also identify that the IR time-table contains significant slack, whereby trains running on certain segments frequently traverse the segments in lesser time than is scheduled. To our knowledge, this is the first study on the run-time delays of trains in IR. We also develop a Web-based application for visualizing traffic-flow in IR.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124554944","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}
