Optimized usage of network resources based on context information

Today an efficient (cost-effective) design and usage of networks is of particular importance. As more and more computer systems become context-aware the question of how context information can be used to improve computer networks arises. In this poster we describe how context information can be used to optimize the usage of resources in a computer network. By means of a mobile payment system we show how these optimization method can be applied

Theory and Evidence on Mergers and Acquisitions by Small and Medium Enterprises

The theory of mergers and acquisitions (M&As) has been developed almost exclusively from the study of large deals by large firms. In this paper we argue that the behaviour and success of M&As by small and medium sized enterprises (SMEs) may be significantly different. Accordingly, we revisit established M&A theories, and develop a theoretical framework, and several testable hypotheses, regarding the distinctive features of SME M&As. Our empirical results support our expectations and show that, compared to large firms, acquiring SMEs: rely more intensively on external growth via M&As; are more likely to be withdrawn, suggesting that SMEs are more flexible, and more able to avoid deals that turn sour; and, finally, SME M&As are more likely to be financed with equity rather than debt, indicating that the influential financial pecking order theory is of less relevance to SMEs.mergers, acquisitions, small and medium sized enterprises

A Comprehensive Experimental Comparison of Event Driven and Multi-Threaded Sensor Node Operating Systems

The capabilities of a sensor network are strongly influenced by the operating system used on the sensor nodes. In general, two different sensor network operating system types are currently considered: event driven and multi-threaded. It is commonly assumed that event driven operating systems are more suited to sensor networks as they use less memory and processing resources. However, if factors other than resource usage are considered important, a multi-threaded system might be preferred. This paper compares the resource needs of multi-threaded and event driven sensor network operating systems. The resources considered are memory usage and power consumption. Additionally, the event handling capabilities of event driven and multi-threaded operating systems are analyzed and compared. The results presented in this paper show that for a number of application areas a thread-based sensor network operating system is feasible and preferable

Improving the Energy Efficiency of the MANTIS Kernel

Event-driven operating systems such as TinyOS are the preferred choice for wireless sensor networks. Alternative designs following a classical multi-threaded approach are also available. A popular implementation of such a multi-threaded sensor network operating system is MANTIS. The event-based TinyOS is more energy efficient than the multi-threaded MANTIS system. However, MANTIS is more capable than TinyOS of supporting time critical tasks as task preemption is supported. Thus, timeliness can be traded for energy efficiency by choosing the appropriate operating system. In this paper we present a MANTIS kernel modification that enables MANTIS to be as power efficient as TinyOS. Results from an experimental analysis demonstrate that the modified MANTIS can be used to fit both sensor network design goals of energy efficiency and timeliness

Letter from E. J. Utz to Martin Cross Regarding Membership Rolls, August 6, 1956

This letter dated August 6, 1956, from Acting Commissioner of the United States (US) Department of the Interior to Three Affiliated Tribes Tribal Chairperson Martin Cross, concerns tribal membership rolls and the closing date for enrollment applications. Utz expresses concern that tribal members were not given enough time to submit applications for enrollment. Utz requests additional information for children who have submitted for enrollment and requests additional information for each rejected enrollment application. This letter was copied to US Senator William Langer. There are some handwritten notes on the letter.https://commons.und.edu/langer-papers/1879/thumbnail.jp

Letter from E. J. Utz to Chairperson of the Three Affiliated Tribes Tribal Business Council, August 6, 1956

This letter, dated August 6, 1956, from Acting Commissioner of the United States (US) Bureau of Indian Affaris E. J. Utz to the chairperson of the Three Affiliated Tribes Tribal Business Council indicates that two copies of membership rolls of the Three Affiliated Tribes have been presented for approval. These rolls are to be used in the distribution of funds authorized by US Public Law 533. Utz references the council\u27s closing of membership date, noting that prospective applicants were not given enough notice. Utz notes as well that the list of rejected memberships has caused concern. and requests additional information for each person rejected for membership. This letter was copied to United States (US) Representative Usher Burdick.https://commons.und.edu/burdick-papers/1322/thumbnail.jp

BurstProbe: Debugging Time-Critical Data Delivery in Wireless Sensor Networks

In this paper we present BurstProbe, a new technique to accurately measure link burstiness in a wireless sensor network employed for time-critical data delivery. Measurement relies on shared probing slots that are embedded in the transmission schedule and used by nodes to assess link burstiness over time. The acquired link burstiness information can be stored in the node's flash memory and relied upon to diagnose transmission problems when missed deadlines occur. Thus, accurate diagnosis is achieved in a distributed manner and without the overhead of transmitting rich measurement data to a central collection point. For the purpose of evaluation we have implemented BurstProbe in the GinMAC WSN protocol and we are able to demonstrate it is an accurate tool to debug time-critical data delivery. In addition, we analyze the cost of implementingBurstProbe and investigate its effectiveness
