Typical steel deck-concrete slab floor systems used in multi-story steel construction require intermediate filler or support beams (14 in. or deeper) and are limited to span of 8-12 ft depending on deck depth. The goal of the research was to develop and validate innovative long span floor systems capable of spanning up to 30 ft with total depths up to 12 in. or less. Several long-span floor systems were conceived and considered. These floor systems were evaluated based on their ability to achieve certain performance objectives. To accomplish these objectives, the project has been conducted in four tasks. The first task focused on conducting a literature review and survey of existing long-span slab systems. This task was conducted to determine the state-of-art for existing floor systems in steel construction. It helped in identifying existing solutions that have been proposed or implemented in steel construction. The second task of the research focused on conceptual development and design of long span floor systems. A suite of different floor system types were developed and proposed. The systems were ranked by the researchers and an oversight committee based on their technical merit and potential to achieve the prescribed performance objectives. The systems were analyzed and designed using analytical tools and methods including the finite element method (FEM), numerical analysis, and existing design codes. Based on the rankings, floor systems were selected for further development and experimental validation. The third task for the research project focused on the experimental validation of the floor system candidates. The testing focused on three different aspects for the floor systems. The aspects included strength and serviceability characteristics at ambient temperature levels, the fundamental heat transfer of certain specimens, and the effects of combined mechanical and thermal loading. The fourth task focused on numerical investigations and analytical parametric studies of the long-span floor system candidates. Analysis methods were developed and used for structural evaluation and evaluation for floor vibrations. Three different systems were found to present merit as potential long span systems. Two used 7.5 in. deep steel decks acting composite with either a 2.5 in. or 3.5 in. concrete slab on top to achieve 30 ft spans with a 10 or 11 in. depth. The other modified existing steel deck-concrete slab systems with new type of self-shoring system to achieve 30 ft spans with a 12.5 in. depth.

A precise estimation of wind intensity and direction is important for many applications. Authors, thanks to a consolidated experience in marine robotics, are building a sail propelled marine drone for a sustainable monitoring of wide sea areas. In particular, sail propulsion assures a near to infinite autonomy since limited energy demand of on board electronic can be assured by renewable sources such as solar cells. However, to correctly manage a sail system, a correct estimation of wind intensity and its direction is essential. Conventional anemometers make use of delicate mechanical moving parts, are therefore not suitable to work autonomously in difficult environments such as the marine one. Commercial ultrasonic anemometers represent a valid alternative but their cost, weight and size need to be optimized for the proposed application which is a cheap, light and relatively small drone. In this work the authors redesigned both acoustic and electronic system to meet the required sp...

‘Dabba Hub’ is an exciting new lunch Tiffin service that would cater to the growing need for homely tasty food by students residing in the buzzing township of Manipal. Manipal University being one of the largest and well know universities across India and the globe is a top choice for many students both domestic and international. As per the information available on the official Manipal university site as of today is the home to over 28,000 students. Out of this 28,000 around 80% are students who have relocated to Manipal from different states of India. Around 2100 of the total count are international students who are in Manipal as a part of exchange programmes or full time courses.Here at Dabba Hub we will be providing the students with a list of delicious homemade dish items which they can mix match to form their week’s lunch menu. The prepared food would then be delivered to the customers at the designated locations at the common lunch time. We at Dabba Hub believe that the market of Manipal can be broadly segmented into two categories. The students residing in hostels and the students are non-hostilities that are living in their own accommodations but not with family. The new venture requires a start-up funding of INR 5 lakhs which will be obtained through the application of a term loan. The term loan is expected to be paid over a period of 3 years.The loan would be split in into a working capital loan of 1 lakh and a term loan of 3 lakhs. There will a self - investment of 1 lakh

Epileptic seizures are a type of neurological disorder that affect many people worldwide. Specialist physicians and neurologists take advantage of structural and functional neuroimaging modalities to diagnose various types of epileptic seizures. Neuroimaging modalities assist specialist physicians considerably in analyzing brain tissue and the changes made in it. One method to accelerate the accurate and fast diagnosis of epileptic seizures is to employ computer aided diagnosis systems (CADS) based on artificial intelligence (AI) and functional ∗Corresponding author Email addresses: afshin.shoeibi@gmail.com (Afshin Shoeibi ), navidghassemi@mail.um.ac.ir (Navid Ghassemi), khodatars1marjane@gmail.com (Marjane Khodatars), mahbube.jafari@yahoo.com (Mahboobeh Jafari), parisamoridian@yahoo.com (Parisa Moridian), ralizadehsani@deakin.edu.au (Roohallah Alizadehsani), alikhadem@kntu.ac.ir (Ali Khadem), yinan.kong@mq.edu.au (Yinan Kong), assefzare@gmail.com (Assef Zare), gorriz@ugr.es (Juan M...

Pressure sensors based on diamond membranes were designed and tested for gas pressure measurement up to 6.8 MPa. The diamond film (2” diameter, 6 μm thickness)—grown by microwave plasma chemical vapor deposition on a silicon substrate—was a starting material to produce an array of membranes with different diameters in the 130–400 μm range, in order to optimize the sensor performance. Each 5 mm × 5 mm sensing element was obtained by subsequent silicon slicing. The fixed film thickness, full-scale pressure range, and sensor sensitivity were established by a proper design of the diameter of diamond membrane which represents the sensing element for differential pressure measurement. The pressure-induced deflection of the membrane was optically measured using a Fabry-Pérot interferometer formed by a single mode optical fiber front surface and the deflecting diamond film surface. The optical response of the system was numerically simulated using geometry and the elastic properties of the ...
