Sparse tables have many uses. Sparse matrices, for instance, are abundant in linear algebra problems ([VDV 88]). Finite state machine representations, such as parsing DFA's, are often represented as 2-dimensional tables which are mostly empty ([DEN 84]). In [AOE 82], an efficient implementation of trie-trees is described that represents nodes as arrays of constant size. Thus a trie tree can be ...

Pneumothorax, a life-threatening disease, needs to be diagnosed immediately and efficiently. The prognosis, in this case, is not only time-consuming but also prone human errors. So, an automatic way of accurate diagnosis using chest X-rays the utmost requirement. To date, most available medical image datasets have class-imbalance (CI) issue. main theme study solve problem along with proposing a...

This study quantifies whole-body vibration on a range of the transportations used in Cairo, Egypt. Subway (Metro), car and bus are the important transportations in Cairo. They are well-known public transportations and play an important role for the human to travel from one place to another. High magnitude of whole-body vibration formed by these transportations may cause diseases and health prob...

We investigated pathogens in the parasitic honeybee mite Varroa destructor using nanoLC-MS/MS (TripleTOF) and 2D-E-MS/MS proteomics approaches supplemented with affinity-chromatography to concentrate trace target proteins. Peptides were detected from the currently uncharacterized Varroa destructor Macula-like virus (VdMLV), the deformed wing virus (DWV)-complex and the acute bee paralysis virus...

The human discomfort from combined noise and vibration has been investigated with a new perspective. concept in perturbation effect adopted to formulate novel predictive model of vibration. A psycho-physics experiment designed identify the which caused by stimulus. involved twelve (12) subjects. Each subject was imposed random order total 42 combinations seven (7) levels (X, 61, 71, 77, 84, 87,...

Variable damping shock absorbers have received extensive attention for their efficient vibration reduction performance, and air springs also been widely used in high-end commercial vehicles due to nonlinear stiffness characteristics. This paper presents a novel semi-active cab suspension integrated with an spring variable electromagnetic damper (A-EMD). The (EMD) prototype was designed, manufac...

Abstract Background This paper proposes a method for designing passive suspension system that determines the optimal settings while offering feasible performance near an active system. A mathematical model of nonlinear quarter car is developed and simulated control optimization in MATLAB/Simulink ® environment. The input road condition Class C Road, vehicle moves at 80 kmph. Fuzzy logic (FLC) a...

Çalışmada yolcu otomobili türü bir taşıtla karayolu - demiryolu hemzemin geçidi (DHG) geçişlerinde maruz kalınan ve insan sağlığını olumsuz etkileyen Tüm Vücut Titreşimi (TVT) seviyeleri araştırılmıştır. Öncelikle çalışmada geometrileri bilinen bazı yol profillerinde farklı hızlarda titreşim ölçümleri yapılmış bu veriler yardımıyla sayısal ortamda taşıtın tepkilerini verebilecek dinamik model k...
