Utilization of the lateral accelerated cross-wind to improve the cooling performance of a natural draft dry cooling tower
Authors: Wang Weiliang , Lyu Junfu , Zhang Hai , Liu Qing , Yue Guangxi , Ni Weidou
Published: September 2019

Cross-wind degrades the performance of a natural draft dry cooling tower
(NDDCT). Based on the basic affecting mechanism, this paper introduces a
wind collecting approach. By using a wind collecting duct, the lateral flow
acceleration of cross-wind is broken up, and the lateral flow kinetic
energy is utilized to increase the lateral and rearward static pressure
outside the radiator inlet. By adoption of a CFD model, the effect of the
wind collecting approach is investigated comprehensively. It is found that
the wind collecting ducts could improve the pressure distribution around the
radiator bundle, reinforce the lateral air intake, and reduce the intensity
of mainstream vortices, so as to enhance the ventilation rate of a NDDCT.
For an outstanding performance, the two-duct wind collecting scheme is
suggested, which may assure a NDDCT working in an approximately wind free
manner in all investigated cross-wind range, and increase the ventilation
rate by ~63% under the high cross-wind condition, which may reduce the
overall coal consumption by 23500~33500 tons annually for a 660 MW
coal-fired unit. The numerical results are confirmed by a hot state
modelling experiment conducted in a wind tunnel.
How the urban environment affects the microclimate and the building energy demand for the City of Rome
Authors: Vallati Andrea , Mauri Luca , Colucci Chiara
Published: September 2019

Urban heat island has significant impacts on buildings? energy consumption.
The phenomenon is associated with increased urban air temperatures compared
to the air temperature of the surrounding rural or suburban areas. The
ambient air temperature growth due to climate changes and the urban heat
island phenomenon are dramatically increasing the cooling demand in
buildings. This is worsened by irradiation conditions, construction
technologies, and subjective comfort expectations. This paper examines the
impact of the urban environment on the energy demand of buildings,
considering the case of two districts of the city of Rome, Italy: one is
representative of a central zone, the other of a rural zone. Weather data
were then used to calculate the thermal demand of a typical Italian
building, ideally located in the monitored areas of the city. Standalone
building with modified weather file was modeled in TRNSYS. Results show that
urban heat island intensity causes an increase in cooling demand up to +33%
for the urban area (+20% for the rural area) compared to the demand
calculated using weather data from airportual areas. On the other hand,
urban heat island intensity has a positive effect on heating demand which
turns out to decrease up to -32% for the urban area (-14% for the rural
area).
Experimental and numerical investigation of thermal field for a motor and related factors sensitivities using combined CFD-Taguchi method
Authors: Liang Xueqi , Luo Huiqiang , Zeng Min , Wu Yining , Wang Qiuwang
Published: September 2019

Over-temperature is a fatal problem when a motor is running. In this work,
the temperature and temperature rise of the motor are investigated
experimentally and numerically. The experiment is conducted by means of both
voltmeter-ammeter method and embedding thermal resistors, to obtain the mean
temperature and the local temperature of the stator coils, respectively.
The numerical calculation is carried out to study the temperature field of
the stator and the rotor, which agrees well with the experimental result.
What?s more, the sensitivity analysis of eighteen factors to the temperature
is investigated using combined CFD-Taguchi method. The main conclusions are
drawn. Firstly, according to the numerical results, the maximal temperature
and the maximal temperature rise at rated speed are 143? and 99 K,
respectively. The values are 145.8? and 90 K, according to the experimental
results, which are lower than the temperature allowed, 180? and temperature
rise allowed, 125 K. Secondly, the sensitivity analysis results suggest that
the key factors influencing the temperature are in sequence the ambient
temperature, the copper loss, the thickness of the layers, the outside
convection heat transfer coefficient of crate, the iron loss at the tooth
and thermal conductivity of the insulation. The contact thermal resistance
and the thermal conductivity of the core in axial direction have little
influence on the temperature. The rank to the temperature rise is similar
except the ambient temperature, which has little effect on the temperature
rise.
Analysis of temperature drops on the wall thickness of a supercritical boiler water-wall tube
Authors: Zima Wieslaw
Published: September 2019

The paper presents selected results of numerical computations related to
simulations of a supercritical power boiler evaporator operation. A
detailed analysis is carried out of temperature drops on the thickness of
the water-wall tube and the tube fin. A comparison is also made between the
results obtained at the fin division into one and two control volumes. The
tube cross-sections analysed along the tube length and including the fins
are divided into 24 control volumes, for which 2-D transient heat conduction
equations are formulated. The 1-D equations describing the principles of
mass, momentum, and energy conservation are solved on the side of the
working fluid. A convective condition, described by an empirical heat
transfer coefficient, is set on the water-wall tube inner surface. The
developed mathematical model is a distributed parameter model. The
numerical computations are performed for a boiler operating in a power
plant in Poland. The analysis takes account of the non-uniformity of the
furnace chamber thermal load along its height.
Verification of applicability of the two-equation turbulence models for temperature distribution in transitional flow in an elliptical tube
Authors: Lopata Stanislaw , Oclon Pawel
Published: September 2019

To increase the efficiency, elliptical tubes are often used in cross-flow
heat exchangers. For these kinds of heat exchangers the flow field in the
tubes exhibits irregularities. Therefore, various flow regimes can be
observed: the turbulent, the transitional, and even the laminar one.
Therefore, applying typical turbulence models for numerical calculations may
cause significant errors, when flow in the heat exchanger tubes is in the
transitional or laminar regime. Hence, the average values of flow velocities
and temperature in heat exchanger tubes can be calculated incorrectly. The
paper presents empirical verification of applying the basic two-equation
turbulence models for a transitional flow of water in an elliptical pipe of
a heat exchanger.
Computational fluid dynamic analysis and validation of the single stage low pressure rotary lobe compressed air expander
Authors: Krawczyk Piotr , Kurkus-Gruszecka Michalina , Mikolajczak Aleksandra , Lapka Piotr , Badyda Krzysztof
Published: September 2019

Technologies using media with relatively low thermodynamic parameters are now
being developed more and more widely. These technologies may be used in
industrial processes in which waste media such as low pressure air or other
gases are available. One of the technologies enabling the use of such gases
is rotary lobe expander. Rotary lobe expanders are compressed gas-powered
devices which produce electricity or mechanical energy. In terms of the
nature of operation, these devices are similar to turbines, but have higher
efficiency at lower operating pressure. Currently, they are applied in
mines as engines or as drives for elevators. The paper covers the CFD model
of the expander and its validation using the literature data on the
industrial device. The mathematical model, geometry, the choice of the
computational grid and the adopted boundary conditions were presented.
Several simulations were carried out for the variable operational
parameters of the device and an attempt was made to assess the correctness
of the assumptions and developed model. Finally, the results with discussion
are presented both in tabular and graphical forms.
Numerical studies on capability to focus solar radiation with mirrors of different curvatures
Authors: Kaczor Zuzanna , Bulinski Zbigniew , Werle Sebastian
Published: September 2019

The article presents the methodology and results of a parametric analysis
performed to investigate the effects of changes in the curvature of the
solar concentrator mirror on its ability to focus the radiation. Working
conditions of the concentrator, i. e. possible values of radiation
intensity, were adopted according to irradiance typical for Poland, and,
therefore, similar to the conditions in many European countries. The
curvatures of examined mirrors were obtained by modification of a parabolic
curve. The calculations were conducted for two cases: when the Sun radiation
falls completely directly and when it's half diffuse. The 2-D simulations
were conducted in ANSYS FLUENT 18.2 software. Discrete ordinates model was
employed to simulate radiation phenomenon. Also, a sensitivity analysis was
carried on discrete ordinates model parameters and density of the
computational mesh. The results allow stating that some of the new
curvatures provide only slightly worse focus than the classical parabolic
shape, but also show greater insensitivity to the increasing share of
diffusive part of radiation. The presented model is a quick and proven tool
for testing new curvatures of solar concentrator mirrors.
Impact of dust and temperature on energy conversion process in photovoltaic module
Authors: Jaszczur Marek , Hassan Qusay , Styszko Katarzyna , Teneta Janusz
Published: September 2019

The impact of the photovoltaic module temperature and natural dust deposition
on the module front surface on the photovoltaic system performance was
investigated. The study was conducted in the city center of Krakow, Poland,
characterized by high pollution and low wind speed. The objective of this
study was to evaluate the photovoltaic module power output decrease and
energy conversion loss as a function of the dust deposition mass and cell
operating temperature. The results show a significant decrease in
photovoltaic efficiency when the mass deposition or temperature increases.
The maximum mass deposition observed for exposure periods of one week on a
single module exceeds 480.0 mg and results in an efficiency loss equal to
2.1%. The results that were obtained enable the development of a
correlation for the efficiency loss caused by dust deposition which is
desired by the system designers.

A comparative analysis of thermal properties of semi-crystalline and
amorphous polymeric materials was carried out. Samples were produced using
3D printing technology on the SIGNAL-ATMAT printer. The following polymeric
materials were used to make the samples: thermoplastic polyurethane
elastomer, acryloni-trile-butadiene-styrene copolymer, Laywood, ethylene
terephthalate, poly (lactic acid). The materials were tested for their
thermal and mechanical properties. The research included the analysis of
thermal properties by differential scanning calorimetry of manufactured
materials. The tensile strength also was determined.
Cenospheric and sand fluidized bed as an environment for waste rubber combustion-comparisons of decomposition dynamics and flue gas emission
Authors: Migas Przemyslaw , Zukowski Witold , Baron Jerzy , Wrona Jan
Published: September 2019

The results of thermal recycling of rubber in the fluidized bed are
presented. Two different types of the bed material were used: sand and low
density spheres (cenospheres). For two bed types, rubber decomposition
time, as the mass and the bed temperature functions, were determined. Time
of the samples residence time was calculated with the assumption, that
reactor and the analytical block may be described with the well-stirred
model. Time of samples decomposition, decrease with increasing temperature,
as expected. It was also established, there are significant deviations
between shirking core model, and obtained results of the residence time as
a mass function. Cenospheric bed application allows to reduce of the process
pressure drop, and caused shift of the gas decomposition products zone to
the deeper region of the bed. Acoustic and optical effects confirmed
significant differences between combustion of sand and cenospheric bed.
Higher frequency of bubbles explosions and reduction of diffusive flames
number were observed during incineration in cenospheric bed. The
relationship between exhaust emission (VOC, CO, NOx) and type of the bed
was not confirmed, the identical situation is observed for the samples
combustion time. In the presented manuscript, the above physical quantity
depends almost completely on sample type and bed temperature.
Simulation of the operation of the car radiator with a laminar, transitional, and turbulent regime of liquid flow in the tubes
Authors: Taler Dawid
Published: September 2019

The results of the simulation of car radiator operation with a large range of
changes in the volume flow rate of liquid inside the tubes were presented.
The change of the flow regime from laminar through transitional to turbulent
flow was taken into account. Semi-empirical and empirical relationships for
the Nusselt number on the liquid-side in the laminar, transitional, and
turbulent range were used. The Nusselt number on the air side was determined
using empirical power-type correlation. The friction factor in the
transition flow range was calculated by linear interpolation between the
values of the friction factor for the Reynolds number equal to 2100 and
3000. The water and air temperature at the outlet of the heat exchanger were
calculated using effectiveness-number of transfer units method. The
heat-flow rate from water to air was calculated as a function of the
water-flow rate to compare it with the experimental results. The calculation
results agreed very well with the results of the measurements.

Authors: Venkataraman Kavita , Pun Vivian , Mohamed Abdalla Z. , Luo Miyang , Wong Caroline , Zong Fangrong , Khoo Eric Y.H. , Tai E. Shyong , Nasrallah Fatima
Published: September 2019

OBJECTIVE

To compare central nervous system (CNS) activation in patients with and without diabetic peripheral neuropathy (DPN) during motor and motor imagery tasks and to correlate activation with functional performance.

RESEARCH DESIGN AND METHODS

Twenty-six participants (13 with DPN, 13 without DPN) underwent functional MRI during three tasks: ankle dorsi plantar flexion (motor task [MT]) and motor imagery tasks of walking on a smooth surface (SMIT) and rough surface (RMIT). Functional assessment included gait analysis, ankle muscle strength, and ankle range of motion.

RESULTS

The tasks activated the sensorimotor, motor preparation, visual processing, and decision-making regions. Activation was significantly lower in patients with DPN than in those without DPN during MT and SMIT but not RMIT. Poor functional performance in patients with DPN was associated with greater activation in motor preparation regions.

CONCLUSIONS

In patients with DPN, CNS responses appear muted compared with patients without DPN, but they remain capable of enhancing CNS activation when tasks are more challenging or when functional deficits are substantial.
Objective Tire Footprint Segmentation Assessment from High-Speed Videos
Authors: Nava Rodrigo , Fehr Duc , Petry Frank , Tamisier Thomas
Published: September 2019

The tire establishes the contact between the vehicle and the road. It transmits all forces and moments to the road via its contact patch or footprint and vice versa. The visual inspection of this contact patch using modern optical equipment and image processing techniques is essential for evaluating tire performance. Quantitative image-based analysis can be useful for accurate determination of tire footprint under various operating conditions. Very frequently, methods used in tire footprint segmentation cannot be assessed quantitatively due to the lack of a reference contact area to which the different algorithms could be compared. In this work, we present a novel methodology to characterize the dynamic tire footprint and evaluate the quality of its segmentation from various video sequences in the absence of a ground truth.
Ny som kroppsøvingslærer – hvordan oppleves det første året i yrket?
Authors: Birkelund Ingrid , Midthaugen Per
Published: September 2019

Artikkelen omhandler nyutdannede kroppsøvingslæreres første år i læreryrket. Oppmerksomheten rettes mot overgangen fra utdanning til yrkesutøvelse, der lærerens opplevelse av relasjonsforhold til elever, foreldre og kollegaer er sentralt. Studiens empiri fremkommer fra semistrukturerte intervjuer med åtte nyutdannede kroppsøvingslærere som arbeidet sitt første yrkesår skoleåret 2013–2014, ved ungdomsskoler og videregående skoler. Resultatene viser at alle de nyutdannede kroppsøvingslærerne følte på et læreransvar som de ikke opplevde i lærerutdanningen. Dette ansvaret handlet om opplevelsen av å stå alene om å ta avgjørelser i utfordrende situasjoner. De opplevde selve kroppsøvingsundervisningen som minst utfordrende i møtet med læreryrket. I tillegg erfarte de å ha et godt og naturlig relasjonsforhold til sine elever. De nyutdannedes relasjon til elevenes foreldre oppleves som problematisk med tanke på ulik forståelse av kroppsøvingsfaget. Lærerne opplevde det også som utfordrende å ta del i skolekulturen, fordi de ikke fullt ut ble akseptert som likeverdige med de erfarne kollegaene. Dette gjorde det utfordrende å samarbeide med de erfarne lærerne på skolen.
English abstract
The article deals with newly qualified physical education teachers’ experiences from their first year as professionals. Here, attention focused on the transition from education to professional life, and the teacher’s experience of relationships with students, parents and colleagues. The study’s empirical material emerges from eight semi-structured interviews, where the sample consisted of graduates of physical education teachers who worked their first school year 2013–2014, at middle schools and high schools. The findings of the study shows that the newly qualified teachers felt a teacher responsibility that they did not experience in teacher education. This responsibility was about the experience of standing alone in making decisions in challenging situations. They experienced physical education lessons as least challenging in the face of the teaching profession. In addition, they experienced having a good and natural relationship to their students. The teachers’ relation to students’ parents were perceived as problematic in terms of the graduates and their parents’ different understanding of physical education. Teachers experienced it as a challenge to take part in the school culture, because they are not fully accepted as the equals of their experienced colleagues. This made it challenging to influence and collaborate with the experienced teachers at the school.

ANALISIS PENDAPAT IMAM MADZHAB TENTANG WAKAF TUNAIDAN IMPLEMENTASINYA DI INDONESIA
Authors: Ja'far A Khumedi
Published: September 2019

Wakaf merupakan salah satu ibadah kebendaan yang penting, yang secara ekplisit tidak memiliki rujukan dalam kitab suci Al-Quran, akan tetapi keberadaannya diilhami oleh ayat-ayat Al-Qur’an.Pada saat mulanya wakaf meliputi berbagai benda, yakni masjid, mushalah, sekolah, tanah pertanian, rumah, took, kebun, pabrik roti, bangunan kantor, gedung dan lain-lain. Seiring dengan kebutuhan dana untuk pengentasan kemiskinan yang sangat besar dan lokasinya tersebar di luar daerah para wakif tersebut, timbulah pemikiran untuk berwakaf dengan uang, hal inilah yang pada akhirnya menimbulkan pro dan kontra dikalangan imam madzhab.Perbedaan pendapat di kalangan Imam Madzhab tentang wakaf tunai adalah menurut  Madzhab Hanafi, Maliki, dan Hambali wakaf benda bergerak diperbolehkan asalkan sudah menjadi urf (kebiasaan) di kalangan masyarakat dan mendatangkan manfaat, seperti mewakafkan buku, mushaf dan uang. Sedangkan menurut Madzhab Syafi’i tidak boleh mewakafkan dinar dan dirham (uang) karena dinar dan dirham akan lenyap dengan dibelanjakan dan sulit untuk mengekalkan zatnya, selain perbedaan tersebut ada juga persamaan dikalangan imam madzhab terhadap wakaf uang tunai diantaranya benda wakaf (harta wakaf) diharuskan ta’bid (kekal) dan pemanfaatan benda tersebut harus terus menerus (dawaam).Kata kunci; wakaf, empat imam madzhab, uang tunai
AKURASI NILAI WAKTU IHTIYATH DALAM PERHITUNGAN AWAL WAKTU SALAT
Authors: Jayusman Jayusman
Published: September 2019

Dalam perhitungan awal waktu salat secara umum biasanya ditambahkan waktu ihtiyath agar azan dikumandangkan ketika awal waktu salat itu telah benar-benar telah masuk. Misalnya ketika awal waktu salat Subuh; fajar Shadiq telah benar-benar terbit, ketika awal waktu salat Zuhur; matahari benar-benar telah tergelingir ke langit bagian barat, ketika awal waktu salat Maghri; matahari benar-benar sudah terbenam, dan ketika awal waktu Isya; syafaq benar-benar telah hilang. Adanya tambahan waktu ihtiyath berguna sebagai antisipasi agar daerah paling barat daerah tersebut dalam melaksanakan ibadah secara bersamaan dengan seluruh warga kota atau daerah tersebut. Para ulama Falak berbeda pendapat tentang nilai ihtiyath dalam perhitungan awal waktu salat. Bagaimanakan konstruksi pemikiran para ahli Falak tentang ihtiyath dalam penentuan awal waktu salat? Dan Bagaimanakah tinjauan ilmu Falak terkait efisiensi nilai ihtiyath dalam penentuan awal waktu salat? Dari  paparan sebelumnya, dapatlah  kita simpulkan sebagai berikut: Ulama Falak Tradisional dan ulama Dahulu cenderung memberikan nilai  ihtiyath dalam perhitungan awal waktu yang besar. Hal ini karena jadwal salat yang mereka hisab cenderung untuk daerah atau kota tersebut dan daerah sekitarnya. Sedang ulama Falak sekarang  memberikan nilai ihtiyath yang lebih kecil  dengan pertimbangan keutamaan salat di awal waktu.Besaran ihtiyath dalam perhitungan awal waktu salat harus mempertimbangkan: luas daerah atau kota yang dihitung awal waktu salatnya dan acuan koordinat kota atau daerah yang dijadikan patokan perhitungan.Kata Kunci: Ihtiyath, Awal Waktu Salat

Published: September 2019

Introduction: The base surface roughness of slot bracket can affect friction in tooth movement. There are ISO-certified and non-ISO-certified stainless steel brackets on the market. Thus orthodontists must be careful in choosing the right bracket. This study was aimed to evaluate the differences of the surface roughness of ISO-certified and non-ISO-certified Roth 0.022 inch stainless steel bracket with the parameter of S a (average roughness). Methods: This research was a laboratory observational. Samples were taken randomly as many as 32 brackets divided into two groups, each consisted of two bracket brands. Surface roughness measurements were performed using an atomic force microscope (AFM), then the data were analysed by ANOVA test (p < 0.05) and Post-Hoc analysis. Results: The ISO-certified bracket has an S a value smaller than the non-ISO-certified bracket. There was a significant difference in the surface roughness of the ISO-certified and non-ISO-certified slot bracket base (p < 0.05). Conclusion: The ISO-certified bracket has a smoother base surface than the non-ISO-certified bracket base.Keywords: Surface roughness, stainless steel slot bracket, atomic force microscope

Authors: Praptiwi Yenni Hendriani , Prayitno Natanael Dwi , Sukmasari Susi
Published: September 2019

Introduction: Molar Incisor Hypomineralisation (MIH) is an enamel defect with white, yellow or black colour due to minerals insufficient during tooth development. The abnormality of prismatic enamel structures and tooth hypersensitivity on patients with MIH may disturb the success rate of restoration. The objective of this research was to determine the prevalence of MIH in primary school children. Methods: A cross-sectional study with purposive sampling on 619 primary school children at Pasteur Urban Village of Bandung City, Indonesia. All dentition were scored using the European Association of Paediatric Dentist (EAPD) MIH scoring sheet, and oral hygiene status assessment with simplified OHI. All data were descriptively described using distribution table. Results: Distribution of MIH on total of 619 children were scored as follows: 0,1,1a, 2, 2a, 3, 4, 5, 6, 7, 8, 9,10 (0 = free enamel defect; 6, 7, and 8 = alteration to non MIH; 1 -5 and 9 -10 = MIH) with frequencies 417(67.36%), 39(6.30%), 60(.65%), 13(2.10%), 0(0.00%), 7(1.13%), 0(0.00%), 4(0.65%), 0(0.00%), 26(4.20%), 58(9.36%), 0(0.00%), and 49(7.91%) respectively. Conclusion: Prevalence of children with MIH in primary school is quite high (19% (118 out of 619 participants)). The highest prevalence is found at the 11 years old group with 49 participants (36.84%), while the prevalence in boys (83 (62.4%)) is found to be higher than girls (50 (37.59%)).Keywords: Prevalence, Molar Incisor Hypomineralisation (MIH), primary school children

Introduction: Tooth loss is a condition that occurs in most of the world's population. The most common causes of tooth loss are caries and periodontal disease. Periodontal disease can usually increase or getting worse by bad habits such as smoking. Smoking accelerates the course of periodontal disease and decreases salivary secretion, whereby increased the risk of caries incidence. Some components of the cigarette’s smoke that can accelerate the course of periodontal diseases are nicotine and tar. The purpose of this study was to determine the difference in the number of tooth loss in smokers and non-smokers. Methods: This study was a cross-sectional study. The sampling method was by the tables of Isaac and Michael, involving 78 smokers and 78 non-smokers in the village of Monmata Lhoong District. Results: Analysis was performed using the Mann-Whitney test. The result showed a significant difference between tooth loss in smokers and non-smokers (p < 0.05). Conclusion: The average value of tooth loss number in smokers is higher (96.47) than the non-smokers (60.53).Keywords: Tooth loss, cigarette, periodontal disease, nicotine, smoker, non-smoker

Introduction: Several researchers have been stated that the right prognosis of oral squamous cell carcinoma (OSCC) can be achieved through assessment of tumor clinical staging and tumor histopathological grading as well. The use of biomarker in histopathological grading is obviously helpful to ensure the prognosis. Objective of this study was to determine the correlation between expression of Ki-67 and histopathological grading of OSCC. Methods: A retrospective study was conducted by assessing 20 cases of paraffin-embedded OSCC derived from the Department of Pathology Anatomy of Hasan Sadikin Hospital Bandung in 2013. The OSCC performing was stained by hematoxylin-eosin. While, antibodies Ki-67 was used in immunohistochemistry reaction to determine the relation of expression of Ki-67 with histopathologic grade of OSCC for predicting a prognosis. Results: The result show that distribution of Ki-67 expression were vary from 20% to 80% in each case. Ki-67 intensity was also distributed from weak, moderate and strong. Conclusion: There is a significant correlation between Ki-67 immunoexpression and the histopathological grading of squamous cell carcinoma (p < 0.01), thus, Ki-67 can be used to predict a prognosis.Keywords: Immunoexpression, Ki-67, prognosis, oral cavity squamous cell carcinoma

Data Mining in Elite Beach Volleyball – Detecting Tactical Patterns Using Market Basket Analysis
Authors: Wenninger Sebastian , Link Daniel , Lames Martin
Published: September 2019

Sports coaches today have access to a growing amount of information that describes the performance of their players. Methods such as data mining have become increasingly useful tools to deal with the analytical demands of these high volumes of data. In this paper, we present a sports data mining approach using a combination of sequential association rule mining and clustering to extract useful information from a database of more than 400 high level beach volleyball games gathered at FIVB events in the years from 2013 to 2016 for both men and women. We regard each rally as a sequence of transactions including the tactical behaviours of the players. Use cases of our approach are shown by its application on the aggregated data for both genders and by analyzing the sequential patterns of a single player. Results indicate that sequential rule mining in conjunction with clustering can be a useful tool to reveal interesting patterns in beach volleyball performance data.

Three inertial measurement unit (IMU) based tennis sensor systems from BABOLAT (PURE DRIVE PLAY, POP) and HEAD (Tennis Sensor) and a camera-based system (PlaySight) were tested with respect to the question whether the information about the number of strokes by swing type and spin type in training exercises and/or matches and the average as well as the maximum speed of the service per session are reliable. Subsequently, the question whether the mechanical properties of the BABOLAT PURE DRIVE PLAY racket are the same as the mechanical properties of the BABOLAT PURE DRIVE racket without IMU was addressed.

For swing types in standard exercises the results are acceptable for forehand groundstrokes, backhand groundstrokes and services but not for volleys. In a match environment we find inacceptably high errors (>10%) for the number of strokes for forehand and completely inacceptable levels for volley. The wrist-based IMU of BABOLAT POP has not reached an acceptable accuracy at all. For spin types the results are acceptable. The large variances in service speed assessment between devices make it doubtful whether any of them may be used for the control of training processes aiming at increasing the average service speed The mechanical properties of the BABOLAT rackets with and without IMU are quite the same.
The Line in the Sand for British Strength Sports. No Second Chances and the Creation of a Drug Free for Life Ethos
Authors: Crisp Philippe
Published: September 2019

Performance enhancing drugs (PEDs) crises in sport provide stories for the mass media. From individuals such as Ben Johnson and Lance Armstrong, to countries and organisations such as Russian Athletics and Major League Baseball. More recently, research has emerged that suggests that those who take drugs, even the once, are permanently advantaged over those who never have (Egner et al., 2013; Eriksson, 2006). This has expanded existing arguments related to PEDs, even extending debate to one that argues that PED use should be monitored and legalised in order to create a level playing field – as opposed to ‘banning’ athletes. In contrast, there are varying reasons for the rationale of ‘clean’ sports. In the first kind of discussion related to this the central premise is often about health concerns and PED use. In the second discussion, we hear much about cheating, unfairness, and the perversion of sport (Schneider & Butcher, 2000). At the present time, the World Anti-Doping Agency (WADA) police PED use in sport and use Anti-Doping Rule Violations (ADRVs) that allow a sliding scale of transgressions with lifetime bans not given in the first instance of a failed test. Put simply then, these ADRVs do not facilitate a system for those not wishing to compete with others who, at any time, have used PEDs. However, in the 1980’s a number of people in Britain made the decision to distance themselves from what they saw as significant doping in British and international Weightlifting. They achieved this through creating competitive strength organisations dedicated to a drug free for life ethos. In this paper I draw on the experiences and reflections of some of these key people, and contend that it was the ideology of fairplay that influenced this movement, and that the rules on PED use should not be fully authoritative and determinate.
Beyond Budgeting – A Fair Alternative for Management Control? - Examining the Relationships between Beyond Budgeting and Organizational Justice Perceptions
Authors: Olaf Schmitz Sven , Agnieszka Michniuk , Thomas Heupel
Published: September 2019

Since the seminal work of Chris Argyris research has realized that the design of Management Control Systems (MCS) has a significant impact on the social framework of an organization. This influence has been discussed in literature for decades. But there has been no holistic alternative for budget related MCS until the development of Beyond Budgeting (BB). Even though BB proponents claim that BB empowers organizations to become more adaptable, efficient and fair and is able to reduce unethical behaviors, BB has not been adopted by a considerable amount of organizations. One reason for this conservative attitude of organizations might be the lack of a framework that makes it possible to assess the possible advantages of BB for a specific organization. Current research suggests evaluating MCS in terms of their impact on organizational justice perceptions. Building on these new empirical findings, our paper tries to contribute to a better understanding of the potential advantages and disadvantages of BB by assessing the impact of BB characteristics on organizational justice perceptions. After identifying BB core characteristics, these characteristics are assessed regarding their impact on organizational justice perceptions. Partial least squares regression is applied to evaluate the relationship between BB core characteristics and organizational justice perceptions. Our results suggest that applying BB might enhance informational and interpersonal justice perceptions and therefore be beneficial for knowledge-based organizations.
Family Entrepreneurship in India’s ‘Diamond City’: A Phenomenological Research
Authors: Babu Vimal
Published: September 2019

The history of family run business in Surat, India is more than 350 years now. However, over the last several decades, it has been observed that family run enterprises in Surat have not been able to scale up the business by untapping opportunities in international markets. The paper aims to explore the experiences of family-run enterprise owners in their attempt to grow their businesses in Surat. Given the stagnant growth trajectory, less expansion, and minimal diversification over the last several decades, the researcher is intrigued to study the experiences of these family-run enterprise owners. As a phenomenological research study, there is only one question: What experiences have these enterprise owners faced in a family-run enterprise as they attempt to grow their businesses? Non-leading prompts were asked to encourage participants to expand their responses to lead to a deeper understanding of those experiences. As respondents, seventeen family-run enterprise owners have been contacted for In-Depth Interview (IDI). The respondents were from diamond, textile and restaurant business in Surat. The study aided in identifying existing challenges and strengths making the whole experience of family-run enterprise owners unique, diverse and different from the conventional businesses operating in different industry. The findings indicate that the potential of family-run enterprises have not been harnessed to its fullest due to prevailing mediocrities, sub-standard practice, sophisticated and disoriented business procedures and system. Organization Development (OD) interventions would be effective in unearthing deeper issues and problems amongst these family-run enterprises in Surat.
