This paper addresses the stability of the switched systems with discrete and distributed time delays. By applying Lyapunov functional and function method, we show that, if the norm of system matrices Bi is small enough, the asymptotic stability is always achieved. Finally, a example is provided to verify technically feasibility and operability of the developed results. Keywords—Switched system,...

We present an operable definition of focus which is argued to be of a cognito-pragmatic nature and explore how it is determined in discourse in a formalized manner. For this purpose, a file card model of discourse model and knowledge store is introduced enabling the decomposition and formal representation of its determination process as a programmable algorithm (FDA). Interdisciplinary evidence...

A case of villous adenoma of the common hepatic duct causing obstructive jaundice, where the diagnosis was made by ultrasound guided percutaneous biopsy is reported. At surgery ultrasonography was used to define the extent and operability of the tumour.

Wireless Networks are most appealing in terms of deployment over a wide range of applications. The key areas are disaster management, industrial unit automation and battlefield surveillance. The paper presents a study over inter-operability of MANET (Mobile Ad-Hoc Network) protocols i.e DSDV, OLSR, ZRP, AODV over WSN (Wireless Sensor Network) [10]. The review here covers all the prevailing prot...

In an environment of continuous and rapid evolution, software design methodologies must incorporate techniques and tools that support changes in software artifacts. In the FERUS project, we are developing a tool targeted at software designers that integrates a collection of operations on algebraic specifications written in the CASL language. The scope of FERUS includes not only modification of ...

Pulmonary arterial hypertension (PAH) is a common complication of congenital heart disease, and is now predominantly among patients with uncorrected left-to-right shunts. A growing population is characterized by persistent or recurrent PAH after surgical or interventional correction of left-to-right shunts; the latter having a worse prognosis than other forms of PAH associated with congenital h...

Fatty acid methyl esters prepared from canola, palm, soybean, and sunflower oils by homogenous basecatalyzed methanolysis were stored for 12 months at three constant temperatures ( 15, 22, and 40 C) and properties such as oxidative stability, acid value, kinematic viscosity, low temperature operability, and iodine value were periodically measured. Oxidative stability was significantly reduced u...

Archaeological site park construction is the protection approach of large site which has the most realistic meaning and operability, in order to reduce the complexity of the construction; this paper puts forward a modeling scheme of Daming Palace archaeological site park k based on the 3 d modeling technology. Firstly, it sets up material point model of Archaeological site, and then forms a cul...

This article traces the strategic initiatives that Walmart undertook over the last decade to implement its ambitious vision of selling more sustainable products. This effort has been characterized by a gradual shift away from customer-facing initiatives aimed at labeling sustainable products toward supplier-facing initiatives targeted at improving environmental or social performance without rai...
