Analyzing Conflict Freedom For Multi-threaded Programs With Time Annotations

Avoiding access conflicts is a major challenge in the design of multi-threaded programs. In the context of real-time systems, the absence of conflicts can be guaranteed by ensuring that no two potentially conflicting accesses are ever scheduled concurrently.In this paper, we analyze programs that carry time annotations specifying the time for executing each statement. We propose a technique for verifying that a multi-threaded program with time annotations is free of access conflicts. In particular, we generate constraints that reflect the possible schedules for executing the program and the required properties. We then invoke an SMT solver in order to verify that no execution gives rise to concurrent conflicting accesses. Otherwise, we obtain a trace that exhibits the access conflict.Comment: http://journal.ub.tu-berlin.de/eceasst/article/view/97

Creating a registration database using Microsoft Access 97

Every business or organization that conducts any type of training, whether on a small or large scale, must deal with logistical issues. There are several ways of keeping track of relevant and important information, including anything from paper based systems to off the shelf computer applications. Very often, these methods are cumbersome or not applicable to the needs of the organization. This research project focuses on the customization of training registration information and logistics for a specific company, for the purposes of this paper called XXXX, using a database. Specifically, a Microsoft Access database was created to keep track of the desired registration information, in a clear and easy to use format. The registration database keeps track of specific information on all employees, classes created, and the schedules for those employees scheduled to take training through company XXXX

R-PEKS: RBAC Enabled PEKS for Secure Access of Cloud Data

In the recent past, few works have been done by combining attribute-based access control with multi-user PEKS, i.e., public key encryption with keyword search. Such attribute enabled searchable encryption is most suitable for applications where the changing of privileges is done once in a while. However, to date, no efficient and secure scheme is available in the literature that is suitable for these applications where changing privileges are done frequently. In this paper our contributions are twofold. Firstly, we propose a new PEKS scheme for string search, which, unlike the previous constructions, is free from bi-linear mapping and is efficient by 97% compared to PEKS for string search proposed by Ray et.al in TrustCom 2017. Secondly, we introduce role based access control (RBAC) to multi-user PEKS, where an arbitrary group of users can search and access the encrypted files depending upon roles. We termed this integrated scheme as R-PEKS. The efficiency of R-PEKS over the PEKS scheme is up to 90%. We provide formal security proofs for the different components of R-PEKS and validate these schemes using a commercial dataset

User-centred design of a digital advisory service: enhancing public agricultural extension for sustainable intensification in Tanzania

Sustainable intensification (SI) is promoted as a rural development paradigm for sub-Saharan Africa. Achieving SI requires smallholder farmers to have access to information that is context-specific, increases their decision-making capacities, and adapts to changing environments. Current extension services often struggle to address these needs. New mobile phone-based services can help. In order to enhance the public extension service in Tanzania, we created a digital service that addresses smallholder farmers’ different information needs for implementing SI. Using a co-design methodology – User-Centered Design – we elicited feedback from farmers and extension agents in Tanzania to create a new digital information service, called Ushauri. This automated hotline gives farmers access to a set of pre-recorded messages. Additionally, farmers can ask questions in a mailbox. Extension agents then listen to these questions through an online platform, where they record and send replies via automated push-calls. A test with 97 farmers in Tanzania showed that farmers actively engaged with the service to access agricultural advice. Extension agents were able to answer questions with reduced workload compared to conventional communication channels. This study illustrates how User-Centered Design can be used to develop information services for complex and resource-restricted smallholder farming contexts

Feasibility of Implementing Community Partnerships to Provide Diabetes Prevention Services to Youth

Type 2 diabetes (T2D) in youth has increased as a result of the obesity epidemic. Diabetes prevention programming is needed for youth, at risk for T2D, and their families. However, there is a lack of diabetes prevention services for this population. There is evidence for the benefit of lifestyle modification for decreasing diabetes risk, however there are barriers for youth to access these services in a traditional clinical setting. Our Youth Diabetes Prevention Clinic (YDPC) created partnerships within the community to increase access to diabetes prevention services for at risk youth. YDPC personnel approached community organizations who had the expertise and capacity to partner in needed areas. These partnerships allowed for the development and facilitation of a community-based diabetes prevention group. Youth and their families participated in a 12 week diabetes prevention group. We measured attendance and participant satisfaction with the program. Families attended an average of 5.1 sessions from January to October 2016. Participant satisfaction was collected five times. Physical activity was rated as “awesome” or “good” by 88% of the respondents. The nutrition activities were rated as “awesome” or “good” by 97% of respondents. Physicians and families express a desire for diabetes prevention services, however barriers make it difficult for families to fully participate. Creating partnerships within the community allows for increased access to diabetes prevention services for high-risk, underserved families

Improving the provision of financial services to micro-entrepreneurs, emerging farmers and agribusiness: Lessons from Kwazulu-Natal

Three development finance institutions (DFIs) which operate in KwaZulu-Natal (KZN) province were assessed in 1996/97 to see how they could improve financial viability and outreach to emerging farmers, agribusiness and micro-entrepreneurs. Improved service quality and emphasis on mobilising savings would help clients and enable the DFIs to diversify their portfolios. Better access to branches and lower loan approval times (improved screening and administrative procedures) could also lower client transaction costs. Charging a suitable interest rate spread is necessary but not sufficient for lenders to achieve subsidy independence. Reducing arrears through stricter loan contract enforcement (borrower accountability for loan repayment, lower collateral specific risks, secure and transferable collateral) will also promote financial viability. Providing both savings and loan services together would reduce borrower access costs, and allow savings to serve as a form of collateral and borrower information for lenders.Agricultural Finance,
