Abstract: Socio-technical transition is a gradual but continuous process of a holistic shift in the social and technical components of a regime. Socio-technical transitions have defined pathways along which transition processes occur. This paper offers a descriptive analysis of the transition process that occurred in the commercial road transport sector in Maiduguri city, the capital of Borno state, Nigeria. The motorcycle mode of passenger transport used to be the dominant means of local travels since year 2000 up till 2011, when the machine was finally banned by the government for security reasons. At the same period, the tricycle technology was fully developed in niches and subsequently grew to occupy the space created by the absence of the motorcycle and eventually became the dominant vehicle in the mass transport regime. The transition dynamics involved was analysed using socio-technical transition pathway theory (the multi-level perspective) and a wide range of data on historical population of commercial passenger transport vehicles in Maiduguri, collected from field survey study. It was found that the motorcycle-tricycle transition pathway involved a complete de-alignment of the regime in the absence of a significant re-alignment dynamics. Thus, the technological change was a radical one whose pathway involved partial characteristics of de-alignment/re-alignment scenario.

Abstract: In this paper, forced transverse vibrations of an elastic hinge-supported Timoshenko beam are considered, taking into account the rotational motion caused by a periodically oscillating concentrated load moving along the beam at a constant speed v. This problem is of practical interest in connection with the study of forced transverse vibrations of bridges. The bridge span is considered here as a Timoshenko beam of constant transverse cross-section. The problem is solved by the method proposed earlier using combined conditions, including dynamic action on the Timoshenko beam and rotational motion relative to the bending wave front. The solution of the problem is built in the form of a number of own forms of vibrations. Two types of forced transverse vibrations and new resonance frequencies are obtained. The purpose of this study is to assess the effect of the identified new forced transverse vibrations for bridges and compare these results. With the solutions obtained by previous authors. To show at which new resonant frequency obtained in bridges new resonance phenomena arise. New dynamic phenomena in bridges caused by a periodically oscillating concentrated load moving along the beam at a constant speed, play an important role in bridge design. This work is a new calculation scheme for the design of bridges.

Abstract: Remote network management and Network Access Control (NAC) are of immense interest to industry since it supports decision making in management and control, and eventually end-user satisfaction. The purpose of this project is to classify a successful remote network management and access control tool for remotely managing a network and network access control at the College of Technology Education, Kumasi. This study utilized remote management tools and network access control techniques such as SSH client, PacketFence and Remote Desktop applications to carefully troubleshoot issues that pertained to the administration of the network of College of Technology Education. The entire system was deployed based on Linux operating system architecture with various workstations and hand-held smart devices as clients; providing real-time network access to network support administrators to remotely resolve problems identified on the network. These systems were also implemented to ensure the operation of security systems and implementation of an effective network access control through the use of Captive Portal. The researcher recommended that since the implemented tools and techniques were able to successfully authenticate user/devices access to the LAN of the College of Technology Education, Kumasi, institutions, organizations etc. should adopt these techniques for network protection and user access control to ensure effective network policy enforcement.
