This study reports an experimental investigation of pool boiling (PB) heat transfer performance hybrid (two types particles) and mono (single-particle) nanofluids consisting Boron nitride (BN) Silicon dioxide (SiO2) nanoparticles (NPs). While (HNFs) were prepared in a total particle concentration 0.05 vol.% with four different percentages these two NPs (are 0.01/0.04, 0.02/ 0.03, 0.03/0.02, 0.0...

The severe drought of 1983–1984 in the Sahel region, and its socio-economic impacts for people relying on farming had consequence first major gold rush at Koma Bangou southwestern part Niger. Initiated 1984, panning activities were interrupted from 1989 to 1999 with exploration permits assigned mining industry. site was reclassified year-end as a artisanal resumed until present-day. Gold such o...

Hyperspectral images (HSIs) are one of the most successfully used tools for precisely and potentially detecting key ground surfaces, vegetation, minerals. HSIs contain a large amount information about scene; therefore, object classification becomes difficult task such high-dimensional HSI data cube. Additionally, HSI’s spectral bands exhibit high correlation, creates dimensionality issues as we...

در این مقاله، به‌منظور رفع برخی محدودیت‌های شناسایی ساختمان تصاویر چندطیفی، از دادة SAR به‌منزلة مکمل استفاده می‌شود. روش پیشنهادی، برای استفادة هم‌زمان اطلاعات مفید رادار و استراتژی مبتنی‌بر تلفیق تصاویر، با هدف ساختمان، مطرح همچنین، ازآن‌جاکه انتخاب ویژگی نقش بسزایی طبقه‌بندی عوارض دارد، اغلب روش‌های مرسوم رایج زمینه، مانند الگوریتم ژنتیک، نیازمند داده‌های آموزشی‌اند؛ اما دردسترس‌نبودن همیشگی...

Various pushbroom imaging spectroscopy systems experience low-frequency array effects that are often referred to as spectral curvature effect or smile/ frown and keystone interferences [1, 2]. The detector elements in a pushbroom system are arranged on a rectilinear grid, therefore dispersing the slit onto the straight rows of detector elements leads to spatial misalignment of the wavelength an...

Porto, the institutional repository of the Politecnico di Torino, is provided by the University Library and the IT-Services. The aim is to enable open access to all the world. Please share with us how this access benefits you. Your story matters. ABSTRACT Increasing the selectivity of the detection system in surface electromyography (EMG) is beneficial in the collection of information of a spec...

Using the stable metalloradical Mn(CO)3(CNArDipp2)2, we report the formation of manganese-main group complexes via the single-electron functionalization of main group halides. The reactions occur in a simple 1 : 1 stoichiometry, and demonstrate the utility of using stable open-shelled organometallics as precursors for metal-main group compounds. This has enabled the preparation of manganese com...

Primary sarcomatoid squamous cell carcinoma (S-SCC) of pharynx is a very rare tumor. A 77-year-old woman presented with sore throat. Laryngoscope revealed an infiltrating tumor of lower pharynx. The tumor was ulcerated and measured 3 cm × 4 cm × 3 cm. The tumor was invasive and involved the surrounding tissues. Biopsies showed sarcomatous malignant spindle cell proliferation as well as invasive...

Reflectance and emittance spectroscopy in the near-infra red and short-wave infra red offers a rapid, Inexpensive, non-destructive tool for determining the mineralogy of rock and soil samples. Hyperspectral remote sensing has the potential to provide the detailed physico-chemistry (mineralogy, chemistry, morphology) of the earth’s surface. This information is useful for mapping potential host r...
