Cylindrical thin-walled tubes due to construction and easy installation, high energy absorption capacity are used in the automotive industry as an impact energy absorber. However, the main weakness of cylindrical tubes is in the high initial peak load. Therefore, in this paper, to overcome this weakness, a buckling initiator is used at the top of the tube. This buckling initiator is a steel rod...

The phenomenon of spiral pair synchronization by oscillating strips (Nozaki-Bekki solution) in a 2D CGLE is investigated analytically. The equations describing the interaction of the strips with one another and with spirals are derived. Analysis of the equations shows that under certain conditions the strips lead to frequency and phase locking of the spirals. In this case the spiral pair (dipol...

As instability from Afghanistan increasingly escalates into Pakistan, can improved India-China relations be a primer for security in the region? Acts of terrorism and destabilisation are now daily occurrences in Pakistan, against the country‟s population, army, police and intelligence services. Given Pakistan‟s political-military basis this appears to be a growing existential threat not only to...

OBJECTIVE This study used nationwide data to determine the prevalence of self-monitoring of blood glucose (SMBG) among all non-institutionalized persons living in Norway and to estimate the prevalence of SMBG among diabetes patients, the frequency and cost of SMBG, and the use of different glucometers. METHODS This retrospective, descriptive study is based on data of sales of glucometer strip...

IMPORTANCE Self-monitoring of blood glucose is a costly component of care for diabetes mellitus, with unclear benefits for patients not taking insulin. Veterans with dual Department of Veterans Affairs (VA) and Medicare benefits have access to test strips through both systems, raising the potential for overuse. OBJECTIVES To examine the patterns of test strip receipt among older veterans with...

Boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), eradication programs typically equip pheromone traps with an insecticide-impregnated kill strip. These strips are intended to kill captured insects, thereby simplifying trap servicing and reducing the loss of weevils from predation and escape. However, the effectiveness of kill strips has not been extensively evaluated...

This work addresses the problem of efficiently learning action schemas using a bounded number of samples (interactions with the environment). We consider schemas in two languages— traditional STRIPS, and a new language STRIPS+WS that extends STRIPS to allow for the creation of new objects when an action is executed. This modification allows STRIPS+WS to model web services and can be used to des...
