A tree-shaped graphene-based microstrip multiple-input and multiple-output (MIMO) antenna for terahertz applications is proposed. The proposed MIMO designed on a 600 × 300 ?m2 polyimide substrate. provides wide impedance bandwidth of 88.14% (0.276–0.711 THz) due to the suggested modifications in configuration. design parameters like total active reflection coefficient (TARC), mean effective gai...

A two-stage stochastic programming model is formulated for a distributed scheduling problem with scenario tree structure. The model allows independent and self-interested job agents to request resources in an asynchronous fashion. Rather than an exact starting time, the central agent gives a time window for one coming job immediately. The final schedule is made based on the total weighted tardi...

A 70-year-old man referred for cataract surgery, had on examination a palette of colored needle-shaped opacities in the cortex and anterior nucleus of the lens, consistent with unilateral Christmas tree cataract. This type of cataract result from the accelerated breakdown of membrane associated proteins. The peptides and amino-acids accumulate in the lumen of the reticular meshwork, and cystine...

the traditional algorithms do not meet the latest multiple requirements simultaneously for objects. Density-based method is one of the methodologies, which can detect arbitrary shaped clusters where clusters are defined as dense regions separated by low density regions. In this paper, we present a new clustering algorithm to enhance the density-based algorithm DBSCAN. This enables an automatic ...

In this paper, we establish a novel duality relationship between node-capacitated multiflows and tree-shaped facility locations. We prove that the maximum value of a tree-distance-weighted maximum node-capacitated multiflow problem is equal to the minimum value of the problem of locating subtrees in a tree, and the maximum is attained by a half-integral multiflow. Utilizing this duality, we sho...

The ancient Indian systems of medicine (AYUSH – Ayurveda, Yunani and Siddha) had explored many medicinal plants which can cure many diseases. The extracts of the medicinal plants possess remarkable biological perspectives. Rain tree (Samanea saman) is one of the tropical tree which possess a wide variety of pharmacological activities. The size of the rain tree generally attains maximum height o...
