Hyperspaces and Superspaces: Linearity and Boundedness
Abstract: Continuing the previous research, we analyze constructions of hyperspaces and superspaces elaborating classifications of such spaces. The main emphasis is on linear hyperspaces, which are formed over linear spaces with additional structures such as norms and seminorms. Linear hyperspaces are constructed over multiseminormed linear spaces and their properties are studied. In particular, it is demonstrated that a linear hyperspace over a multiseminormed linear space is a multihyperseminormed linear space. This …

The Impact of Linear Infrastructure on Land Utilization using GIS
Abstract: In all urban centers of the Tigray region and the nation as whole, there is inefficient urban land utilization and development. The bottlenecks in the supply of serviced land are caused by inadequate provision of infrastructure and services. Moreover, the government often provides arterial infrastructure, leaving the provision of secondary and tertiary infrastructure to individuals or private sector developers. As a result private sectors or individuals assembled raw land only. …

Review on Free Piston Linear Alternator
Abstract: This study presents the development methodology of the Free-Piston Linear Alternator/Generator (FPLG). The FPLG is a free-piston combustion engine with an integrated linear generator. The engine can be used as a range-extending device in an electric vehicle. Unlike conventional internal combustion engines, a free-piston linear engine has no a crankshaft, and thus the pistons move freely in the cylinder. This allows a free-piston linear engine to easily adjust the compression …

Abstract: The Electromagnetic Propulsion Train project efforts on developing a model that proves linear motion using exactly controlled electromagnetic forces. Dissimilar conventional railway systems that depend on mechanical drives, traction motors, and wheel–rail friction, this model uses a coordinated arrangement of electromagnets positioned along the track to generate attractive and repulsive forces, which together produce the essential propulsion. This method reduces dependence on mechanical movement and highlights the possible of magnetic …
