By an unbalanced Hadamard matrix we mean a matrix H,, = (hii) such that (i) hii = l/fi or -I/fi, (ii) H, is orthogonal, and (iii) the number of positive entries exceeds the number of negative entries in each row. In particular it is well-known that the dimension n must be an even perfect square if the number of positive entries is the same in each row. It is easy to show that the number of posi...

In this study, new evidence is presented of marked sex differences in the distribution of insecure attachment patterns in middle childhood. Attachment was assessed with the Manchester Child Attachment Story Task (MCAST) in a sample of 122 Italian 7-yearolds. The four-way distribution of attachment patterns was significantly unbalanced, with insecure boys more often avoidant (27%) than ambivalen...

An unbalanced translocation of chromosome 1 and 7 (t[1;7]) associated with neurological phenotype and brain malformation has rarely been reported. This clinical report describes 3 siblings with brain malformations and a 13.5 Mb duplication of 1q42.3q44, and a 7.6 Mb duplication of 7q36.1q36.3 detected by array comparative genomic hybridization. This unbalanced t(1;7) was found to be inherited f...

We describe a methodology for modelling the performance of parallel algorithmic skeletons and illustrate it using a new skeleton which supports set membership classiication problems in Constructive Solid Geometry. These problems are characterised by potentially unbalanced tree structures with data-dependent computations at the nodes. The skeleton achieves good parallel eeciency even with highly...

In this paper, a control system for the operation of a doubly fed induction generator (DFIG), feeding an unbalanced three-phase load is presented. The load unbalance is compensated using the front-end converter. The control system is based on positive and negative sequence components of current. MATLAB Simulation results obtained from a DFIG system and are presented and discussed in this paper....

Results: A structural chromosomal abnormality was observed in 95 cases. The most frequently observed structural abnormalities were balanced translocations with a frequency of 53.7% (51 cases) followed by unbalanced translocations (16.8%), inversions (11.6%), supernumerary marker chromosomes (8.4%), duplications (4.2%), deletions and ring chromosomes (2.1%) and complex translocation (1.1%). rare...

of 16 hr produced a loss of cell viability accompanied by an inhibition of DNA synthesis. Continued synthesis of RNA and protein suggests an unbalanced growth similar to that previously observed with 5-fluorodeoxyuridine, excess thymidine, and 1-/8D-arabinofuranosylcytosine. A threefold increase in thymidine kinase activity was observed as a result of unbalanced growth following the exposure of...

Among traditional wireless sensor routing algorithm like LEACH, problems like unbalanced energy consumption in wireless sensor network, node losing efficacy because of large energy consumption, period uncertainty of periodic cluster head and unbalanced energy consumption between clusters come into being. Aiming at problem of unbalanced energy consumption between wireless sensor clusters, uneven...

In multicategory classification, standard techniques typically treat all classes equally. This treatment can be problematic when the dataset is unbalanced in the sense that certain classes have very small class proportions compared to others. The minority classes may be ignored or discounted during the classification process due to their small proportions. This can be a serious problem if those...

This paper presents a distributed video streaming framework using unbalanced multiple description coding (MDC) and forward error correction. In the proposed video streaming framework, two senders simultaneously stream complementary descriptions to the receiver over different paths. To minimize the overall distortion and exploit the benefits of multi-path transport when the characteristics of ea...
