The Internet of Things (IoT) is widely used in advanced logistic systems. Safety and security of such systems are utmost important to guarantee the quality of their services. However, such systems are vulnerable to cyber-attacks. Development of lightweight anomaly based intrusion detection systems (IDS) is one of the key measures to tackle this problem. In this paper, we present a new distribut...

Lightweight Clay Aggregate (LWCA) is a kind of highly porous granular particle which often used as lightweight backfilling geomaterials. However, the easy breakage LWCA plays negative role in its geotechnical application. This study focuses on internal structure and compressive behavior single using experiments numerical simulations. The uniaxial strength loading stiffness attributed to special...

There is growing interest in thin, lightweight, and flexible energy storage devices to meet the special needs for next-generation, high-performance, flexible electronics. Here we report a thin, lightweight, and flexible lithium ion battery made from graphene foam, a three-dimensional, flexible, and conductive interconnected network, as a current collector, loaded with Li(4)Ti(5)O(12) and LiFePO...

The design of cement slurry for horizontal wellbores is challenging as it must present very high quality cement slurry properties e.g. zero free water, less than 50 cc API fluid loss value, appropriate rheology and yield point for effective displacement, adequate compressive strength, which is critical for lightweight slurries, and finally stable cement column behind casing. The main objective ...

This paper presents a memory-efficient auxiliary data structure for ray tracing called a lightweight bounding volume hierarchy, or LBVH. The new data structure reduces memory requirements in three ways: using implicit indexing, limited precision numbers, and a high branching factor. We show that LBVHs can be nearly as effective as standard bounding volumes in terms of speed while using signific...

SMIng (next generation structure of management information), an information model for network management, is a prospective structure of management information. When deploying the multi-agent systems to network management environments, we have established a lightweight self-contained knowledge model based on RDF (Resource Description Framework) and its extensions. We also present an implementati...

Central tower concentrating solar power systems are moving to the forefront become technology of choice for generating renewable electricity, but their widespread implementation is limited by cost. Heliostats contribute almost 50% plant’s cost and thus most significant element in central systems. For both large small-area heliostats, drive elements demonstrate largest these While large-area hel...

gears are one of the most critical components in power transmission system of an automobile and also many rotating machinery. many studies have been conducted on optimum gear design. the main objective is to design different aluminium metal matrix composite spur gears before and after optimization. aluminium metal matrix material composites are preferred mostly due to their low density. also th...

By conducting low-reversed cyclic loading tests, this paper explores the load-bearing performance of frame-supported multi-ribbed lightweight wall structures. The finite-element software (OpenSees) is used to simulate the process with the shear wall width (at the frame-supported layer) and different hole opening approaches (for multi-ribbed lightweight walls) as variables. The conclusions refle...
