Background & objectives: The disposal of hazardous waste in the environment, which is usually done by burying it in a special landfill, requires a set of environmental standards and special economic, social and managerial considerations. Improper landfills can have negative health, economic, and environmental effects. In this regard, the present study seeks to find a suitable landfill for speci...

this study examined the effect of general and specific practice on the presence of a special skill. 24 healthy university students with no history of basketball were selected. after a pretest, they performed constant and variable practice (in constant and variable groups) for 5 weeks and 3 sessions per week. a performance test was conducted at the end of every week and retention and transfer te...

Mobile computers often bene t from software which adapts to its location For example a computer might be backed up when at the o ce or the default printer might always be a nearby one In many existing systems location triggered actions are only possible for speci c applications or with special infrastructure This paper describes lcron a system which supports user con gurable actions triggered o...

central granular cell odontogenic tumor) cgcot) of the jaw is an exceedingly rare benign odontogenic neoplasm with 35 reported cases in the literature. among these, very few studies have focused on the cone-beam ct features of cgcot. here, we report a case of an asymptomatic cgcot in a 16-year-old girl and focus on the cone-beam ct features. only 36 cases of this lesion, including this one, hav...

In this paper we propose the Online Connected Facility Location problem (OCFL), which is an online version of the Connected Facility Location problem (CFL). The CFL is a combination of the Uncapacitated Facility Location problem (FL) and the Steiner Tree problem (ST). We give a randomized O(log n)-competitive algorithm for the OCFL via the sample-and-augment framework of Gupta, Kumar, Pál, and ...

Localization is widely used in Wireless Sensor Networks (WSNs) to identify the current location of the sensor nodes. A WSN consist of thousands of nodes that make the installation of GPS on each sensor node expensive and moreover GPS may not provide exact localization results in an indoor environment. Manually configuring location reference on each sensor node is also not possible for dense net...

This paper describes a new model for sharing location info for mobile users. This approach can operate without the need for disclosing identity info to third party servers. It could be described as a safe location sharing model. The proposed approach creates a special form of distributed database that splits location info and identity information. In this distributed data store identity info is...
