Customer satisfaction and sale performance in New York State brewery tasting rooms

AbstractThe US craft brewery industry has grown steadily in recent years before the 2020 COVID-19 pandemic. The majority of small, independently owned craft breweries rely on tasting rooms for revenues and profits. Using data collected from a survey of tasting room visitors from 21 craft breweries in New York, this research investigates factors influencing visitors’ customer satisfaction (CS) and the link between brewery tasting room CS and sales performance. The results show that brewery interior ambience, beer tasting execution, and friendliness and knowledge of servers are the main factors influencing CS in tasting rooms. Furthermore, results suggest that higher CS levels increase visitors’ purchase likelihood and beer purchase amounts (by volume and value). These findings indicate that breweries should focus on such factors as strengthening staff training, enhancing tasting room ambience, and improving beer tasting execution that have the highest positive influence on CS to increase sales. This study has implications for the rapidly growing craft brewery industry in the USA.

Class Room Ambience Measurement using Ai Technique

The word SMART is popular in everyday activities which is meant for city, road, vehicles and home through the integration of IOT (Internet of Things) and ICT (Information and Communication Technology). It is possible by using the above, our everyday activities can be monitored and recorded using advanced devices in our work environment. It is suggested to have such tools in the education institutes to have better classroom and lab infrastructure for teaching and learning environments. Now a day’s many technologies exist and our aim is to integrate all the existing and new technologies to develop an embedded system application to make the classroom to be more smart and automated. In this context we will study how to design and develop the class room ambience measurement using AI technique. The machine is so smart by identifying the empty chairs and calling individual persons and occupy the place near to others so that the fan, light usage can me minimum which is possible through intelligent device and its prototype model is proposed here.

Smart Framework for Automatic Control of Home Appliances Using IoT

With the advent of the 21st century, comfort and efficiency started becoming a part of a common man’s life. Virtual assistants like Amazon Alexa and mobile applications like Google Assistant have tremendously helped in making Home Automation Systems more effortless and orderly. Efforts are still being made for better intra-connection of our homes. Home automation has created a great impact in the field of the Internet Of Things. In this paper, we have used the pre-existing technology of Alexa Echo to make Home Automation more cost-effective by enabling non-smart devices to react to the virtual assistant. In this framework, we proposed a smart node (relay) that can remotely control the connected electrical gadget using text/voice commands. The status can be monitored and controlled by the Alexa app remotely without the need for physical voice commands to Alexa. Further, room ambience, as well as emotion-based lighting, can be provided.

Paper-Based Stable Broad Band Optical Detector Made from Mixed Cation Organic Perovskite Halides

We report a paper-based photodetector made from mixed cation organic perovskite halide MA1–xFAxPbI3 (MA = methylammonium (CH3NH3); FA = formamidium CH(NH2)2). The detector shows a substantial photogain and photoresponse at low illumination intensity (<10 μW/cm2) and a broad band response that extends from 300 to 800 nm at the optimum substitutional level with x = 0.4. A peak responsivity of 0.27 A/W in the paper photodetector was observed at a wavelength of ∼775 nm at a bias of 5 V. The responsivity stayed above 0.1 A/W for a broad optical wavelength range of 550 to 825 nm that covers a good range of the visible spectra. The detector has a low dark current (<10–9 A) at highest bias of operation and an rms current noise of ≤10 pA. The mixed halide detector was grown on conventional paper using a one-pot chemical process. The detector reported here is stable at a room ambience and does not deteriorate under prolonged exposure to illumination. It combines the high response of MAPbI3 and the stability of FAPbI3. The paper photodetector is useful in a number of applications needing flexible and disposable detectors, and the power requirement even at full operation is <0.5 μW at a low bias (<5 V) making it compatible with battery-powered operation.

SITA standard testing with Humphrey visual field analyzer versus full threshold testing with frequency doubling perimetry: a comparison of patient preference and perception

Purpose: To compare patient preference for Swedish Interactive Threshold Algorithm (SITA) standard 24-2 protocol in Humphrey visual field analyzer (HVF) and full threshold N-30 protocol in frequency doubling perimetry (FDP) by primarily evaluating their perception about the test procedure and test targets along with surveying the factors that influence the patient concentration during perimetry and elements that determine the level of perimetry task difficulty.&#x0D; Methods: This study enrolled a subset of subjects from the Chennai Glaucoma Study. Each subject underwent a comprehensive ophthalmic examination after which they were randomly allocated to perform HVF and FDP with a 30-minute interval between the two procedures. SITA standard 24-2 protocol in HVF and full threshold N-30 protocol in FDP were used. This was followed by the administration of a questionnaire that mainly assessed the components such as (a) the patient preference for test procedure and test targets, (b) the factors influencing the patient concentration during perimetry performance, and (c) the impression about the level of perimetry task difficulty. The patient responses from the survey for each of the subcategories were obtained and analyzed using Chi-square test.&#x0D; Results: A total of 42 subjects with a mean age of 59.7 (SD 9.7) years were included, among which 18 (42.86%) were male and 24 (57.14%) were female. Thirty-two (76.19%) subjects felt both FDP and HVF were easy to perform, eight subjects (19.05%) felt that both perimetry techniques were difficult to perform, and two subjects (4.76%) found FDP procedure was easier than HVF, whereas the distribution was not statistically significant (Chi-square, p = 0.7). Pressing the button as a response to peripheral stimulus perception and inability to maintain steady central fixation for prolonged duration were the most commonly reported factors that influenced the level of difficulty of the perimetry tasks. A dark room ambience set for performing HVF was preferred by 32 (76.20%) subjects.&#x0D; Conclusion: There was no significant difference in the patient preference for test procedure and peripheral test targets. A black central fixation as in FDP and dark room ambience set for HVF were preferred.

A hybrid prediction method on luminous flux maintenance of high-power LED lamps

A hybrid method, applied thermal modeling and temperature measurement, is proposed to estimate the junction temperature (Tj) of high-power light-emitting diodes (LEDs) at system level, and further project long term lumen maintenance of LED lamps. First, 3D finite element modeling on commercial LED lamps is performed based on lamp structure and material information to find a steady and reliable relationship between the junction point and a referenced point on the heat sink. Then, accurate thermal measurement is conducted on the heat sink to calibrate and verify the finite element model. The predicted Tj of LEDs from modeling, in conjunction with LM-80 luminous maintenance data using TM-21, is applied to project the luminous flux depreciation at the system level. The proposed approach is validated by aging tests at room ambience. Results show the thermal resistance modeling can be simplified into a one-dimensional model when a LED lamp operates in a steady situation. Thus, the Tj of LED lamps operating at any specified ambient temperature can be achieved quickly. The estimation method for predicting luminous maintenance of LED lamps is efficient and fast. The proposed method is expected to be useful for the fast qualification of LED lamps.

Audio Analysis &amp; Creating Reverberation Plug-ins In Digital Audio Engineering

In audio engineering, early reflection patterns are not usually variable, such as the user makes a selection from a handful of stored patterns simulating various rooms, halls, chambers and plates, or small room ambience, reflections is variable. To create digital reverb is much more complicated than combining a few digital relay units. The greater the spacing the larger the room sounds. Some difficult problems happened in recording situation is that every acoustic instrument engineers record sounds small or dry because their recording room does not have the same degree and circumstances of acoustic ambience as good as concert halls or venues. As a matter of fact that the same situation is also true of the most professional studios, apart from those with large, live rooms, and most pop music is recorded dry enough, either in a dry environment. In that case, people use close miking technique to get right sound source. Electronic effects units are used to recreate the desired ambience, and by far the most important effects unit of them all is reverberation.

Waiting room ambience and provision of opioid substitution therapy in general practice

To assess whether patients receiving opioid substitution therapy (OST) in general practice cause other patients sufficient distress to change practices--a perceived barrier that prevents general practitioners from prescribing OST. A cross-sectional questionnaire-based survey of consecutive adult patients in the waiting rooms of a network of research general practices in New South Wales during August-December 2009. Prevalence of disturbing waiting room experiences where drug intoxication was considered a factor, discomfort about sharing the waiting room with patients being treated for drug addiction, and likelihood of changing practices if the practice provided specialised care for patients with opiate addiction. From 15 practices (eight OST-prescribing), 1138 of 1449 invited patients completed questionnaires (response rate, 78.5%). A disturbing experience in any waiting room at any time was reported by 18.0% of respondents (203/1130), with only 3.1% (35/1128) reporting that drug intoxication was a contributing factor. However, 39.3% of respondents (424/1080) would feel uncomfortable sharing the waiting room with someone being treated for drug addiction. Respondents were largely unaware of the OST-prescribing status of the practice (12.1% of patients attending OST-prescribing practices [70/579] correctly reported this). Only 15.9% of respondents (165/1037) reported being likely to change practices if theirs provided specialised care for opiate-addicted patients. In contrast, 28.7% (302/1053) were likely to change practices if consistently kept waiting more than 30 minutes, and 26.6% (275/1033) would likely do so if consultation fees increased by $10. Despite the frequency of stigmatising attitudes towards patients requiring treatment for drug addiction, GPs' concerns that prescribing OST in their practices would have a negative impact on other patients' waiting room experiences or on retention of patients seem to be unfounded.

Interfacial microstructure and properties of Sn–0.7Cu–0.05Ni/Cu solder joint with rare earth Nd addition

Interfacial microstructure and properties of Sn–0.7Cu–0.05Ni/Cu solder joints with trace amounts Nd additions have been investigated in this paper. The evolution of interfacial morphology of SCN solder joints with and without the presence of Nd under long-term room ambience was also studied. The greatest improvement to the solderability and tensile strength of SCN- xNd are obtained at 0.05 wt.% Nd. Meanwhile, the morphology and growth of interfacial intermetallic (IMC) layer are greatly improved by adding Nd, and the propensity for IMC spalling from the interface of solder joint is definitely reduced with the presence of rare earth Nd, since the sponge-like structure was completely inhibited in the solder joint containing Nd. In addition, a significant amount of Sn whiskers were present on the surface of NdSn 3 phases in the SCN0.15Nd/Cu solder joints, and the reason for this phenomenon has been briefly discussed.

Observations of continuous tin whisker growth in NdSn3 intermetallic compound

In situ observation of tin whisker growth in NdSn3 compound was carried out by using an optical microscope (OM) and scanning electron microscopy (SEM). The growth rate of Sn-whisker from NdSn3 is shown to be rapid (approximately 8-15Å/s) during exposure to room ambience, and it is accompanied by formation of a new compound, Nd(OH)3, as was confirmed by x-ray diffraction. This reaction between the Sn-RE compound and trace water in room ambience has significant influence on whisker growth. There is an electron irradiation effect on whisker growth; that is, whiskers stopped growing after being observed in SEM. Therefore, it is suggested that OM be used rather than SEM to observe the continuous whisker growth. In discussion, the driving force per Sn atom for whisker growth is estimated as 1 × 1014 N in accordance with the whisker growth rate, and its apparent force originates from a chemical potential gradient between the released Sn atoms and the whisker.

Spontaneous growth of whiskers on RE-bearing intermetallic compounds of Sn-RE, In-RE, and Pb-RE

A phenomenon of the whiskers growth on the bulk rare earth (RE)-intermetallic compounds of NdSn 3, NdIn 3, and LaPb 3 is reported. The whiskers formed spontaneously on all of the RE-intermetallic compounds after exposed to room ambience (21–28 °C/20–56% RH, relative humidity) for several days. Among the samples, the propensity of whisker growth for NdSn 3 is the strongest, on which the tin whiskers were flourishing and covered all of the surfaces after exposed to room ambience for 22 days; while LaPb 3 is the secondary and NdIn 3 is the last one. Observed by SEM, the whiskers were exhibited as different morphology, size, and number density. The XRD analysis confirms the existence of RE(OH) 3 after whiskers formed, also, the weight gain curve of the samples exposed to room ambience supports that a spontaneous chemical reaction of the RE-intermetallic compounds with water in room ambience takes place. In discussion, it is proposed that the fresh metal atoms released by the chemical reaction could be causative to result in nucleation and spontaneous growth of the whiskers, while the anisotropy of crystal structure could be a reason to understand the difference of the whisker growth behaviors between Sn and Pb.

Echo and reverb: fabricating space in popular music recording, 1900-1960

Echo and Reverb is the first history of acoustically imagined space in popular music recording. The book documents how acoustic effects-reverberation, room ambience, and echo-have been used in recordings since the 1920s to create virtual sonic architectures and landscapes. Author Peter Doyle traces the development of these acoustically-created worlds from the ancient Greek myth of Echo and Narcissus to the dramatic acoustic architectures of the medieval cathedral, the grand concert halls of the 19th century, and those created by the humble parlor phonograph of the early 20th century, and finally, the revolutionary age of rock 'n' roll. Citing recordings ranging from Gene Austin's 'My Blue Heaven' to Elvis Presley's 'Mystery Train,' Doyle illustrates how non-musical sound constructs, with all their rich and contradictory baggage, became a central feature of recorded music. The book traces various imagined worlds created with synthetic echo and reverb-the heroic landscapes of the cowboy west, the twilight shores of south sea islands, the uncanny alleys of dark cityscapes, the weird mindspaces of horror movies, the private and collective spaces of teen experience, and the funky juke-joints of the mind.

From ‘My Blue Heaven’ to ‘Race with the Devil’: echo, reverb and (dis)ordered space in early popular music recording

With the dramatically improving fidelity of electric sound recording in the 1920s, aural spatiality – traces of room ambience and reverberation – became a factor in record production. Drawing on prior radio broadcast practice, a split occurred whereby ‘fine’ orchestral musics were recorded with relatively high levels of ambient or atmospheric sound while dance music, popular songs, humorous recitations and other ‘low’ forms were generally recorded with little or no reverberation. Through the 1930s and 1940s, popular recording occasionally, though increasingly, made use of mechanically fabricated echo and reverb to present a kind of sonic pictorialism, especially on singing cowboy and popular ‘Hawaiian’ recordings. Hollywood film sound practice in this period employed similar sonic space-making devices to denote states of terror, mystical revelation and supernatural transformations. The coming of rock ‘n’ roll in the 1950s, with its characteristic big echo and reverb production sounds, may be seen as the radical recombining of these contradictory antecedents, effected in such a way as to allow (and promote) disordered, non-pictorial sound spatialities.
