High-power thyristors with direct light -triggering and integrated protection functions can be utilized advantageously for applications in which several thyristors are connected in series. This applies in particular to High-Voltage DC (HVDC) transmission, Static Var Compensation (SVC), converters for medium voltage drives, and also to certain pulse power applications. Recent progress in both de...

We empirically examine how corporate governance affects the structure of executive compensation contracts. In particular, we analyze the implicit weights of firm performance measures in explaining CEO compensation. We find that weaker corporate governance is associated with compensation contracts that put more weight on accounting-based measures of performance (i.e., return on assets) than on s...

OBJECTIVE This study of Department of Defense (DoD) civilian employees Workers' Compensation (WC) claims for chargeback year 2000 through 2012 aimed to analyze the frequency, rates, and costs of WC claims representing 5% of the DoD annual personnel budget. METHODS A multiyear cross-sectional study of WC claims data identified the top five most frequent causes, natures, and anatomical sites; c...

In recent years, crowdsourcing is increasingly applied as a means to enhance data quality. Although the crowd generates insightful information especially for complex problems such as entity resolution (ER), the output quality of crowd workers is often noisy. That is, workers may unintentionally generate false or contradicting data even for simple tasks. The challenge that we address in this pap...

This paper identifies and analyses a new effect related to the cyclical behaviour of labour supply: Entitled-Worker Effect (EWE). is different from well-known Added-Worker (AWE) Discouraged-Worker (DWE). The EWE consequence one most important institutions: unemployment benefit (UB). We develop model with uncertainty about results job-seeking transaction costs linked such search process, showing...

In this paper, we describe our approach to implicitly parallelizing programs written in a functional subset of Scala characterized by the single assignment rule. Our functional programming model is supported by a functional subset of Scala based on our past experiences with the Sisal language and the functional language level of DrJava. We automatically parallelize functional Scala programs by ...

As one of the successful forms of using Wisdom of Crowd, crowdsourcing, has been widely used for many human intrinsic tasks, such as image labeling, natural language understanding, market predication and opinion mining. Meanwhile, with advances in pervasive technology, mobile devices, such as mobile phones and tablets, have become extremely popular. These mobile devices can work as sensors to c...

Submission of multiple jobs in a distributed and heterogeneous environment is required by applications that rely on the ”public-resource computing” paradigm. We present here a scientific scenario for the analysis of astronomical data, where some nodes are responsible for maintaining and advertising job description files and other so called worker nodes, are dispersed over the Grid to execute th...

Work-sharing in production systems is a modern approach that improves throughput rate. Work is shifted between cross-trained workers in order to better balance the material flow in the system. When a serial system is concerned, a common work-sharing approach is the Bucket-Brigade (BB), by which downstream workers sequentially take over items from adjacent upstream workers. When the workers are ...

Geographically distributed (geo-distributed) datacenters for stream data processing typically comprise multiple edges and core connected through Wide-Area Network (WAN) with a master node responsible allocating tasks to worker nodes. Since WAN links significantly impact the performance of task execution, existing assignment approach is unsuitable low latency high throughput demand. In this pape...
