Waverider, volume 2

The results of a study concerning a High-Speed Civilian Transport Aircraft are discussed. An evaluation of the viability of four configurations is presented. One design considered in the Waverider configuration. The Waverider creates lift at high speeds through the use of shock waves. This shocklift when combined with conventionally created lift provides high lift/drag values at higher speeds than conventional configurations. The Waverider cruises at Mach 5.5, has a range of 6,500 nautical miles, and seats 250 passengers. The aircraft is operable from existing airfields and does not require any special traffic control considerations when operating in controlled airspace

An integrated marketing communications campaign for Sella Uno Garage Cafe

Sella Uno is a home-based cafe located in Malabon City, founded by the Reyes Siblings. From their fully-online beginning, the owners opened a physical location for the cafe in their home garage to allow its customers to experience Sella Uno. They aim to provide its customers with comfort and happiness at a reasonable price point. The cafe specializes in their unique offers of internationally-inspired dishes such as their series of strombollis, pastas, and lattes. Sella Uno believes that its customers should be able to enjoy the high quality and unique flavors they have to offer without much financial worries. Sella Uno was established on May 15, 2021 by the Reyes siblings on the same day it started accepting pre-orders for deliveries. It was on May 22, 2021 when the cafe officially opened its physical location. The cafe operated mostly online due to COVID-19 restrictions, but 10 months after Sella Uno opened the Reyes siblings decided to offer alfresco dining which is currently in the parking space of their home that they have converted to a mini cafe. On March 7, 2020, Sella Uno announced to the public through their facebook account that they have begun selling on the Foodpanda Delivery app and that they could begin placing orders for the cafe through the app on March 24, 2022. The main goal of this integrated marketing plan is to achieve awareness of Sella Uno Garage Cafe and set it as a brand who does not only bring quality food and drinks but also give happy and memorable moments that create special connections. The campaign’s goal is to reinforce the brand equity thus creating unique and relatable content that would appeal to its target market of ages 26-32 years old or the young millennials. The campaign strategy is to not only sell the products to customers but also to give them the feeling of happiness while eating the offerings of Sella Uno. In order for the campaign to instill this feeling - the researcher created seasonal promotional opportunities that caters well to the brand and its focus. This paper focuses and has the primary goal of assisting the client to this research, Sella Uno (Restaurant), in developing further as a business. In-depth market research, including SWOT, PESTLE, and Marketing trends, has allowed the team to identify a number of prospective adjustments that are intended to help Sella Uno grow over time in all facets of their operations. To assist Sella Uno reach its target demographic even further. The marketing plan shown below, includes new themes, menu items, posters, and other advertising efforts to further improve the marketing plan for Sella Uno. The success of all of these suggestions made by the group will depend on the proper usage of these marketing techniques which will be done over the course of the next few months both on-site and online. The sales objective is to gain incremental sales at 5% using various promos within the campaign period from September 2022 to August 2023. This will be supported by the campaign’s promotional activities to gain incremental sales, amounting to P 1,771, 256.10 total projected gross sales. This will be made feasible by following various promotional activities and achieving the brand\u27s objectives such as: educating customers on product offerings, creating brand awareness, and focusing on offline to online efforts and vice versa. Brands can make people happy by following ethical and logical business practices, meeting their target audience\u27s expectations by putting elements that make their customers happy at the top of the agenda, and, on occasion, performing unexpected acts of kindness. It pays to have satisfied, empowered customers. Acceptability, Affordability, Accessibility and Awareness are what makes a consumer entertain and purchase a brand. With this, it is very important for the consumer to accept the brand’s approach to their consumers - how they are presented and what is the brand’s equity or “trademark.” In Sella Uno’s case - happiness is what they are trying to show to their audience - that whenever they go to the store or purchase their product - the comfort and happiness their food would bring would immediately lift their spirits. Affordability - since consumers wanted to be able to afford and yet enjoy the food. Next is accessibility since it is also important for the customers to know that the brand can easily be seen and heard. After all, convenience is what really matters for these customers. Though Sella Uno is located in Malabon - it has different ways on how to reach their target market. Lastly, awareness. Awareness is one of the important things that Sella Uno should achieve in order to gain customers, equity and of course, sales. With the study above Sella Uno should show a diverse marketing collateral, efforts, and promotional activities that would create happiness and positive outlook for the customers to have a full intent on purchasing and visiting the cafe and that would lead to purchase decision and repeat purchase. Sella Uno should also create promotional activities that would not only lead to sales and repeat purchase but also to gain new customers through its promos and activities. These promotional activities should contain relatable content that would capture the attention of the target market. Awareness should be the first step towards the brand as Sella Uno can be considered to be in the introduction level. Sella Uno should also illustrate through their content and promos that even though they are located in Malabon, they are still accessible and easy to reach therefore, their online efforts such as delivery, website and inquiries through social media should be well-maintained

A design tool for matching UAV propeller and power plant performance

University of Minnesota M.S. thesis. May 2013. Major: Aerospace Engineering and Mechanics. Advisors: Demoz Gebre-Egziabher, William L. Garrard. 1 computer file (PDF); xviii, 134 pages, appendix A.A large body of knowledge is available for matching propellers to engines for large propeller driven aircraft. Small UAV's and model airplanes operate at much lower Reynolds numbers and use fixed pitch propellers so the information for large aircraft is not directly applicable. A design tool is needed that takes into account Reynolds number effects, allows for gear reduction, and the selection of a propeller optimized for the airframe. The tool developed in this thesis does this using propeller performance data generated from vortex theory or wind tunnel experiments and combines that data with an engine power curve. The thrust, steady state power, RPM, and tip Mach number vs. velocity curves are generated. The Reynolds number vs. non dimensional radial station at an operating point is also found. The tool is then used to design a geared power plant for the SAE Aero Design competition. To measure the power plant performance, a purpose built engine test stand was built. The characteristics of the engine test stand are also presented. The engine test stand was then used to characterize the geared power plant. The power plant uses a 26x16 propeller, 100/13 gear ratio, and an LRP 0.30 cubic inch engine turning at 28,000 RPM and producing 2.2 HP. Lastly, the measured power plant performance is presented. An important result is that 17 lbf of static thrust is produced.Mangio, Arion L.. (2013). A design tool for matching UAV propeller and power plant performance.

Flying Wing Optimization

Additional contributor: Bernie Mettler (faculty mentor)The flying wing with camber, constant chord, and high aspect ratio is a stable platform and possible to fly in a controllable fashion. The main concern is in turning flight. A vertical fin may need to be used or more sophisticated drag creating control surfaces at the wing tips could be created. Also stabilizing electronics would need to be used for the yaw axis. Large control surfaces must be used to effectively change the shape of the wing and to give ample control in yaw. The weight saved by not having a tail section may be lost by having large control surfaces and more electronics. A good compromise may be to have a vertical fin and large ailerons instead of having drag flaps at the wing tips

The canonical eIF4E isoform of C. elegans regulates growth, embryogenesis, and germline sex-determination

eIF4E plays a conserved role in initiating protein synthesis, but with multiple eIF4E isoforms present in many organisms, these proteins also adopt specialized functions. Previous RNAi studies showed that ife-3, encoding the sole canonical eIF4E isoform of Caenorhabditis elegans, is essential for viability. Using ife-3 gene mutations, we show here that it is maternal ife-3 function that is essential for embryogenesis, but ife-3 null progeny of heterozygous animals are viable. We find that zygotic ife-3 function promotes body growth and regulates germline development in hermaphrodite worms. Specifically, the normal transition from spermatogenesis to oogenesis in the hermaphrodite germline fails in ife-3 mutants. This failure to switch is reversed by inhibiting expression of the key masculinizing gene, fem-3, suggesting ife-3 resembles a growing number of genes that promote the sperm/oocyte switch by acting genetically as upstream inhibitors of fem-3

Assessment of Drinking Water Quality Status and its Impact on Health in Tandojam City

Unsafe drinking water is one of the major concerns in developing countries. The southern Sindh is province of Pakistan that adjoins the Arabian Sea coast where the drinking water quality is deteriorating due to unrefined urban waste and excessive use of agro-chemicals. Present study aimed to assess the quality of ground water source and to compare it with WHO standards. Water borne diseases associated with drinking it in the vicinity Tandojam city were identified. Water from ground water source was sampled at selected locations in the study area. The samples were collected mostly from pumped waters. The samples were analyzed for physico-chemical properties in order to identify the quality problems and suggest safe source for drinking purpose. Findings revealed that the ground water quality in Muzaffrabad colony is deteriorating. The situation was much worse in Muzaffrabad colony, Jam Ghar and Mir colony with high TDS and salty taste, respectively at few sampling locations. In addition, laboratory analysis of the water quality parameters revealed the detail of variation in the groundwater. TDS, hardness, sodium (Na), chloride (Cl) and magnesium (Mg) etc. were considerably beyond the WHO permissible limits. The poor quality of the water has created different waterborne diseases like cholera, diarrhea etc. Moreover, the samples of SAU Colony and Amar Town showed that the water quality of these areas was within acceptable limits according to WHO standards and was suitable for the purpose of drinking
