A single-valued neutrosophic set is a special case of neutrosophic set. It has been proposed as a generalization of crisp sets, fuzzy sets, and intuitionistic fuzzy sets in order to deal with incomplete information. In this paper, a new approach for multi-attribute group decision-making problems is proposed by extending the technique for order preference by(More)
In this paper, we propose new vector similarity measures of single-valued and interval neutrosophic sets by hybridizing the concepts of Dice and cosine similarity measures. We present their applications in multi-attribute decision making under neutrosophic environment. We use these similarity measures to find out the best alternative by determining the(More)
The objective of the study is to present cosine similarity measure based multi-attribute decision making under neutrosophic environment. The assesments of alternatives over the attributes are expressed with trapezoidal fuzzy neutrosophic numbers in which the three independent components namely, truth-membership degree (T), indeterminacy-membership degree(More)
Adrenal myelolipomas are rare benign tumors. Most of the cases are asymptomatic and discovered incidentally. We are reporting a case of myelolipoma involving right adrenal cortex of a 40-year-old woman who presented with abdominal pain. A short review of etiology, clinical features, and differential diagnoses of this neoplasm are also discussed. Radiologic(More)
This paper presents multi-objective assignment problem with fuzzy costs, where all the objectives are to be simultaneously minimized. Here each fuzzy cost is assumed as trapezoidal fuzzy number. To form a single objective problem of a multi-objective fuzzy assignment problem, weights of the objectives have been taken according to their priorities. Yager's(More)

In every field of our real life situations, we deal with a replacement problem, when some items such as machines, medical equipment, military tank, electric bulb etc. or workers need to replace due to their decreased efficiency, failure or break down. To get a more realistic view of a replacement problem, here, we consider that the capital cost (C ~), scrap(More)
We report low-temperature solution-processed p-CuO nanorods (NRs)/n-ZnO NRs heterojunction light emitting diode (LED), exploiting the native point defects of ZnO NRs. ZnO NRs were synthesized at 90 °C by using hydrothermal method while CuO NRs were synthesized at 100 °C by using microwave reaction system. The electrical properties of newly synthesized CuO(More)
Spectrum tuning and meeting low power are the main challenges in impulse radio ultra-wideband (IR-UWB) system while it has the highest level of prospects in contactless and continuous vital sign monitoring. In this paper, an IR-UWB transmitter is designed for the most desirable feature of IR-UWB that is exact spectral tuning along with the lowest energy(More)
Primary cutaneous large B-cell lymphoma, leg type (PCLBCL-LT), is very rare neoplasm presenting on and confined to leg(s). PCLBCL-LT is distinguished from other type of primary cutaneous B-cell lymphoma (PCBCL) by its frequent relapses and poorer prognosis. We report, two cases of PCLBCL-LT, occurring in two younger patients compared to published cases in(More)
