Location analysis to suggest new warehouse for Best Furniture shop

Best Furniture operates as a retail furniture outlet in Hamilton, established in 2015, selling furniture manufactured in China and distributed to New Zealand through a network operated from Australia. While the business has tremendous opportunities to grow and outlast its competition, it does not have enough retail space to store its inventory to effectively service all the customer requests it receives. This research aims at identifying and recommending a location to situate a new warehouse for the business such that its operational capacities can be fully utilized. Qualitative research in the form of interview of business manager, and observation, were used to identify a new location and also to provide guidelines on warehouse management. Based on the research conducted, it is recommended that the business operates it new warehouse from a location proximal to Auckland port. It is also recommended that the business creates and implements a warehouse management process and policy document and utilizes available warehouse management software for efficient management of inventory and to streamline the supply chain after the centre is established

Coverage Path Planning And Control For Autonomous Mobile Robots

Coverage control has many applications such as security patrolling, land mine detectors, and automatic vacuum cleaners. This Thesis presents an analytical approach for generation of control inputs for a non-holonomic mobile robot in coverage control. Neural Network approach is used for complete coverage of a given area in the presence of stationary and dynamic obstacles. A complete coverage algorithm is used to determine the sequence of points. Once the sequences of points are determined a smooth trajectory characterized by fifth order polynomial having second order continuity is generated. And the slope of the curve at each point is calculated from which the control inputs are generated analytically. Optimal trajectory is generated using a method given in research literature and a qualitative analysis of the smooth trajectory is done. Cooperative sweeping of multirobots is achieved by dividing the area to be covered into smaller areas depending on the number of robots. Once the area is divided into sub areas, each robot is assigned a sub area for cooperative sweeping

Enhancing flat plate heat convection using a pair of winglets – The effect of transverse spacing

We can manipulate the prevailing atmospheric wind to enhance the convective cooling of a solar photovoltaic panel and thus its energy conversion efficiency. The transverse spacing (D) of a delta winglet pair was examined for its role in convective heat transfer enhancement. A pair of winglets with an inclination angle of 90° and chord/height (c/h) ratio of 2 was positioned at an attack angle of 30° with respect to incoming wind at a Reynolds number, based on the winglet height, of 6300. The transverse distance, D, was varied from 0 to 3h in 1h increments. The Nusselt number normalized by the reference no-winglet case, Nu/Nu0, was determined from the surface temperature measured by a thermal camera. The D=2h case was found to lead to the largest Nu/Nu0. This significant heat transfer enhancement was explained in terms of vortical flow characteristics detailed at 10h downstream of the winglet pair, where the most potent downwash was induced when D=2h

9-Ethyl-2,3-dihydro-9H-carbazol-4(1H)-one

In the title compound, C28H30N2O2, the cyclo­hexene ring system adopts a sofa conformation. The crystal structure is stabilized by C—H⋯O inter­actions between methyl H atoms of the ethyl substituents and the O atoms of carbonyl groups of adjacent mol­ecules, and by an inter­molecular carbon­yl–carbonyl inter­actions [3.207 (2) Å

2,3,4,9-Tetra­hydro-1H-carbazole

In the title compound, C12H13N, two methyl­ene C atoms of the cyclo­hexene ring are disordered over two sites with occupancies of 0.591 (10) and 0.409 (10); both disorder components adopt half-chair conformations. The crystal structure is stabilized by inter­molecular N—H⋯π and C—H⋯π inter­actions

Functional Outcome of closed metacarpal fractures treated with mini fragment plates and screws: A Prospective study

BACKGROUND: Accurate open reduction and internal fixation of metacarpal fractures are required in unstable fractures where closed treatment technique yield poor functional outcome which usually is less than 5% of hand fractures. Minifragment plates and screws when used in properly selected cases provide rigid fixation allowing early mobilisation of joints and hence good functional outcome. PATIENTS AND METHODS: In 20 patients with closed unstable metacarpal fractures treated with minifragment plates and screws , functional outcome was assessed using American society for surgery of the hand (ASSH) total active flexion (TAF) score over a period of two years in prospective manner. RESULTS: In our study of unstable metacarpal fractures treated with plate osteosynthesis all the cases showed bone union (100%). The functional result is excellent in 80% of the patients (16 of 20 cases), good in 10% of cases (2 of 20 cases), poor in 10% of cases(2 of 20 cases). 2 patients developed superficial wound infection which settled with daily dressing and antibiotics and this does not affect the final outcome. CONCLUSIONS: Plate and screw fixation is a good option for treating closed unstable metacarpal fractures, where other modalities of fixation are less effective, the rigid stable fixation provided by plating withstands load without failure allowed early mobilization and achieved good functional results

[2-(4-Methylbenzoyl)phenyl](4-methylphenyl)methanone

The asymmetric unit of the title compound, C22H18O2, contains one half-mol­ecule, the complete mol­ecule being generated by the operation of a crystallographic twofold rotation axis.
