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...
This paper presents a simple three phase load flow method to solve three-phase unbalanced radial distribution system (RDS). A three phase load flow solution with considering most of load modeling is presented which has good convergence property for any practical distribution networks with practical R/X ratio. It solves a simple algebraic recursive expression of voltage magnitude, and all the da...
This paper proposes a new control scheme for regulating the instantaneous power for pwm boost type rectifiers under generalized unbalanced operating conditions. By nullifying the oscillating components of instantaneous power at the poles of the converter instead of the front-end through solving a set of nonlinear control equations in real time, the harmonics in the output dc voltage can be el...
This paper presents an evaluation of different types and families of multiwavelets in stereo correspondence matching. Different multiwavelet families with different filter types such as balanced versus unbalanced, symmetricsymmetric versus symmetric-antisymmetric are used. Normalized cross correlation is employed to find the best correspondence points and generate a disparity map. In the case o...
This paper presents an analysis of the three-phase self-excited induction generator (SEIG) with staticcompensator {STATCOM) as a voltage regulator. Current controlled voltage source inverter (CC-VSI) is used as STATCOM, which provides fast dynamic response to maintain constant voltage at SEIG terminals during severe load perturbations and acts as a source and sink of reactive power. The perform...
Abstract: Unbalanced mass identification is important for rotor systems. Current methods normally use sensors, which only detect vibration in two-dimensional (2D) space. Actually, the rotor systems vibrate in three-dimensional directions. In this paper, a non-contact method is developed to identify unbalanced mass of rotor systems in 3D space. A stereo video system with a pair of synchronized h...
