A 1.4mW 4.90-to-5.65GHz Class-C CMOS VCO with an Average FoM of 194.5dBc/Hz

A class-C CMOS harmonic VCO maximizes the oscillation amplitude by operating the active devices operating in class C, while the bias-current noise is naturally rejected by the topology. Drawing 1.4mA from a 1V supply, the 0.13µm CMOS prototype exhibits an average phase noise of -130dBc/Hz at 3MHz offset over the 4.90-to-5.65GHz tuning range, for an FoM of 194.5dBc/Hz.

Parallel and Distributed Graph Cuts

Graph cuts methods are at the core of many state-of-the-art algorithms in computer vision due to their efficiency in computing globally optimal solutions. In this paper, we solve the maximum flow/minimum cut problem in parallel by splitting the graph into multiple parts and hence, further increase the computational efficacy of graph cuts. Optimality of the solution is guaranteed by dual decomposit

Model Curriculum for a Bachelor of Science Program in Business Information Systems Design (BISD 2010)

Commentators on Information Systems (IS) education have urged the IS community to develop new and alternative IS curricula. The IS 2002 model curriculum has recently been revised. The new IS 2010 curriculum guidelines for undergraduate degree programs in Information Systems [Topi et al. 2010] has a curriculum structure to accommodate the education of several different professional roles within IS.

Comparative Analysis of Flooding in Gothenburg, Sweden and Mumbai, India: A Review

To cope with flooding in cities, a combination of well working stormwater system and a resilient city is needed. As the future is uncertain, cities have to be built resilient, meaning that they can be flexible and adaptable, as it is not possible to protect the city from floods totally. Green areas in the city can provide resilience, as water can be led here e.g. during heavy rainfall. In this art

Whom and What to Fight? Some Notes and Queries on Indian Farmers Collective Action under Liberalisation and Globalisation

Farmers’ movements arose in Tamil Nadu, Punjab, Karnataka, Maharashtra and U.P in the early 1970s as a result of the broad state intervention in commercial agricultural development, especially the green revolution technology and electrified pump-irrigation. Since the state had already organised farmers in service cooperatives, farmers’ movements took an explicitly political form agitating for bett

Does Collaboration Include or Exclude? Participatory Aspects of Collaboration between Welfare Agencies when Investigating Suspected Child Abuse

Varying degrees of collaboration and consultation in the area of child and family welfare in the public sector has grown rapidly since the 1980s, especially concerning children at risk. Collaboration is understood to provide a more holistic view of the individual's needs, lead to better care and treatment as well as increase knowledge in general. Collaboration in that sense constitute a flexible a

Dynamic Isotropy in 6-DOF Kinematically Constrained Platforms by Three Elastic Nodal Joints

The principle of kinematic design has a wide range of applications e.g. from optical mirror mounts to parallel robots. Despite the importance of dynamic isotropy in the optimization of dynamic performance, a thorough analysis of dynamic isotropy in different kinematic arrangements has not yet been addressed in the literature. Dynamic isotropy, leading to equal eigenfrequencies, is a powerful optim

Performance analysis of coded OFDM on fading channels with non-ideal interleaving and channel knowledge

We investigate the coded bit-error rate (BER) in an orthogonal frequency-division multiplexing (OFDM) system in a Rayleigh-fading channel. The system uses a pilot-based channel estimator and the effects of non-ideal channel knowledge and non-ideal interleaving are analysed. The coded BER is estimated with an analytical method proposed by Cavers and Ho, which involves truncation of the union bound.
