Ship security alert system : a failed effort to protect coastal communities
Merchant ships are now equipped with alert systems intended to prevent acts of terrorism. However, local authorities maybe alerted too late to take effective action. Several steps can be taken to tackle the flaws in the ...
Impacts of bends and ground return vias on interconnects for high speed GHz designs
In the past only critical clock circuits are running at high speed but this is no longer true ...
In-circuit impedance measurement based on a two-probe approach
Most impedance measurement instruments usually measure the impedance of a component or device under no-load condition. Therefore, any non-linear behaviour and other on board circuit components or parasitic are not detected ...
Non-blind audio-watermarking using compression-expansion of signals
One of the advantages of non-blind watermarking scheme is that the original signal must be available to extract the watermark. As such, the possession of the original signal becomes important in the proof of ownership. ...
Advanced fighter purchase : heralding Thai military modernisation programme
Thailand’s recent US$600m purchase of six Swedish JAS 39 Gripen fighters, one Saab 340 aircraft equipped with the Erieye AEW radar systemand a command-and-control system to link the fighters with the Erieye airborne early ...
Tuning the properties of PS-PIAT block copolymers and their assembly into polymersomes
The diblock copolymer polystyrene-b-polyisocyanoalanine(2-thiophene-3-yl-ethyl)amide (PS–PIAT) was prepared by reacting the isocyanide monomer (1) with a Ni(II) initiator complex prepared ...
The sizes of optimal q-ary codes of weight three and distance four : a complete solution
This correspondence introduces two new constructive techniques to complete the determination of the sizes of optimal q-ary codes of constant weight three and distance four.
Improved lower bounds for constant GC-content DNA codes
The design of large libraries of oligonucleotides having constant GC-content and satisfying Hamming distance constraints between oligonucleotides and their Watson-Crick complements is important in reducing hybridization ...
An area efficient high turn ratio monolithic transformer for silicon RFIC
A novel way of manufacturing an on-chip ...
Change without changing : Obama's gate-keeper in defence
President-elect Barack Obama's decision to keep Robert Gates as the United States Secretary of Defence sends the right message to America's partners and will benefit its military. Secretary Gates' leadership and vision ...
