Waste management issues for the UK ready-mixed concrete industry

The UK government has recognised the vital contribution that the construction industry has to play in contributing towards sustainable development. While the issue of hardened concrete waste has received considerable attention, process waste arising from the manufacture of ready-mixed concrete is relatively unexplored. It is apparent that initiatives such as the landfill tax have encouraged UK ready-mixed concrete manufacturers to reduce substantially the amount of waste they produce. Environmental pressures continue to increase and ready-mixed concrete producers are being forced towards a closed loop production system.

Robotics within the teaching of problem-solving

Abstract This paper considers the experiences of teaching on a module where problem-solving is taught first, then programming. The main tools for the problem-solving part, alongside two problem-solving approaches, are tasks using Mindstorm (LEGO, Denmark) robot kits. This is being done as a foundation step before the syntax of a language (Java) is taught to enable a Graphical User Interface (GUI) emulation of a previous robot problem. Results of student evaluation and feedback will be presented and the use of two simulators will be considered.

An Efficient Channel Model for Evaluating Wireless NoC Architectures

Wireless Networks-on-Chip (WiNoCs) have emerged to solve the scalability and performance bottleneck of conventional wired NoC architectures. However unlike communication in the macro-world, on-chip communication poses several constraints, hence there is the need for simulation and design tools that consider the effect of the wireless channel at the nanotechnology level. In this paper, we present a parameterizable channel model for WiNoCs which takes into account practical issues and constraints of the propagation medium, such as transmission frequency, operating temperature, ambient pressure and distance between the on-chip antennas. The proposed channel model demonstrates that total path loss of the wireless channel in WiNoCs suffers from not only dielectric propagation loss (DPL) but also molecular absorption attenuation (MAA) which reduces the reliability of the system.

Review of a Problems-First Approach to First Year Undergraduate Programming

This paper, predominantly discusses the teaching of programming and problem solving to undergraduate first year computing students, using robots/robot simulators and visual programming to emulate the robot tasks. The needs to focus initial programming education on problem solving, prior to the teaching of programming syntax and software design methodology is also considered. The main vehicle for this approach is a robot/robot simulation programmed in Java, followed by the programming of a visual representation/simulation to develop programming skills.

Electronic Online Marking of Software Assignments

With the advent of Virtual Learning Environments (VLEs) and online electronic submission of assignments, computing lecturers are increasingly assessing code online. There are various tools for aiding electronic marking, grading and plagiarism detection. However, there appears to be limited shared advice to computer science tutors (and students) on the effective use of these tools. This chapter aims to stimulate peer-discussion amongst tutors involved in the assessing (marking and grading) of software code. Many United Kingdom (UK) Higher Education Institutions (HEI) are using electronic marking. This chapter discusses the authors’ experience and proposes suggestions for appropriate and effective solutions to the electronic assessment of software code. This will be based on the authors’ experience of electronically assessing code over three academic years and the current advice given to their students.
