Pre- and Post-Processing Algorithms with Deep Learning Classifier for Wi-Fi Fingerprint-Based Indoor Positioning

To accommodate the rapidly increasing demand for connected infrastructure, automation for industrial sites and building smart cities, the development of Internet of Things (IoT)-based solutions is considered one of the major trends in modern day industrial revolution. In particular, providing high precision indoor positioning services for such applications is a key challenge. Wi-Fi fingerprint-based indoor positioning systems have been adapted as promising candidates for such applications. The performance of such indoor positioning systems degrade drastically due to several impairments like noisy datasets, high variation in Wi-Fi signals over time, fading of Wi-Fi signals due to multipath propagation caused by hurdles, people walking in the area under consideration and the addition/removal of Wi-Fi access points (APs). In this paper, we propose data pre- and post-processing algorithms with deep learning classifiers for Wi-Fi fingerprint-based indoor positioning, in order to provide immunity against limitations in the database and the indoor environment. In addition, we investigate the performance of the proposed system through simulation as well as extensive experiments. The results demonstrate that the pre-processing algorithm can efficiently fill in the missing Wi-Fi received signal strength fingerprints in the database, resulting in a success rate of 88.96% in simulation and 86.61% in a real-time experiment. The post-processing algorithm can improve the results from 9.05–10.94% for the conducted experiments, providing the highest success rate of 95.94% with a precision of 4 m for Wi-Fi fingerprint-based indoor positioning.
Generalized Weibull and Inverse Weibull Distributions with Applications

In this thesis, new classes of Weibull and inverse Weibull distributions including the generalized new modified Weibull (GNMW), gamma-generalized inverse Weibull (GGIW), the weighted proportional inverse Weibull (WPIW) and inverse new modified Weibull (INMW) distributions are introduced. The GNMW contains several submodels including the new modified Weibull (NMW), generalized modified Weibull (GMW), modified Weibull (MW), Weibull (W) and exponential (E) distributions, just to mention a few. The class of WPIW distributions contains several models such as: length-biased, hazard and reverse hazard proportional inverse Weibull, proportional inverse Weibull, inverse Weibull, inverse exponential, inverse Rayleigh, and Fréchet distributions as special cases. Included in the GGIW distribution are the submodels: gamma-generalized inverse Weibull, gamma-generalized Fréchet, gammageneralized inverse Rayleigh, gamma-generalized inverse exponential, inverse Weibull, inverse Rayleigh, inverse exponential, Fréchet distributions. The INMW distribution contains several sub-models including inverse Weibull, inverse new modified exponential, inverse new modified Rayleigh, new modified Fréchet, inverse modified Weibull, inverse Rayleigh and inverse exponential distributions as special cases. Properties of these distributions including the behavior of the hazard function, moments, coefficients of variation, skewness, and kurtosis, s−entropy, distribution of order statistic and Fisher information are presented. Estimates of the parameters of the models via method of maximum likelihood (ML) are presented. Extensive simulation study is conducted and numerical examples are given.
Comparison of Grip Strength in Dominant and Non-Dominant hand in Recreational Cyclists

Recreational cycling is sort of sport that requires a decent level of endurance, and cyclists’ riding is determined by several physical abilities, in which muscular strength in upper limb is equally important as the lower limbs. While riding a bicycle, the hand grip turns out to be especially crucial not just for performance and the ability to remain upright in difficult situations and uneven surfaces but also for even moderate endurance and comfort of the rider A total of 60 recreational cyclists, 25-35 years old were included in the study. Grip strength of dominant and non-dominant hand was checked with Jamar hand held dynamometer pre cycling and was checked again after the 20km ride. Normality was checked and Dominant hand data passed the normality test thus, paired t-test was used to determine significance for (p<0.05). For Non-dominant hand readings didn’t support normality to the optimal level (p>0.05) hence non-parametric Wilcoxon signed test was used to determine significance as the samples were dependent. Mann-Whitney test was used to determine significance in Dominant and Non-Dominant hand pre cycling activity as well as comparison of Dominant and Non-Dominant hand post cycling activity, as data was not normally distributed and the samples were independent. (p>0.05). Results showed that there is significant difference in dominant as well as non-dominant hand pre and post riding activity with post cycling grip strength being reduced in both Dominant and Non-Dominant hand than the pre-cycling grip strength. Also, Dominant hand grip strength was more than the non-Dominant hand in both pre and post cycling. Key words: Recreational cyclists, Grip strength, dominant and non-dominant hand, Jamar hand held dynamometer.
Forecasting the Disturbed Storm Time Index

The Disturbed Storm Time (Dst) index is a measure of the magnetic field (in nT) created by the ring current, an electric current carried by charged particles trapped in the Earth’s magnetosphere. The index is calculated from measurements at 4 magnetometer stations near the equator and referenced to zero on “internationally designated quiet days. ” As with other geomagnetic indices, the Dst index exhibits a high degree of correlation from one value to the next. In fact, existing forecast models that strictly use solar wind and interplanetary magnetic field data as inputs have a difficult time matching the performance of simple persistence when evaluating the model by the linear correlation coefficient and the root mean square error between forecast values and actual values. A model using the unscented Kalman filter (UKF) as the forecast engine was developed in an attempt to improve on simple persistence and existing models. This UKF model is very similar to the model we used to forecast the planetary geomagnetic index (Kp) last year (Wetterer et al. [2010]) that outperformed all other existing Kp forecast models. Initial results using this UKF forecast model to forecast Dst shows a similar performance and are detailed in this paper. The UKFbased model offers the opportunity for further forecast improvement by adding new inputs and refining the state and measurement functions in the filter.
Avaliação da composição corporal em adolescentes obesos: o uso de dois diferentes métodos

RESUMO A pletismografia e um metodo rapido e facil para determinacao da composicao corporal que utiliza a relacao inversa entre pressao e volume. O objetivo do presente estudo foi o de comparar os valores obtidos com o metodo pletismografia com os valores observados com o DEXA em uma populacao de adolescentes obesos. Participaram da amostra 88 adolescentes pos-puberes de ambos os sexos, com idades entre 15 e 19 anos (17,01 ± 1,6) ingressantes de um programa de atividade fisica multidisciplinar. Os voluntarios foram submetidos a uma avaliacao da composicao corporal em dias distintos dentro da mesma semana, pelo metodo de pletismografia e outra avaliacao pelo metodo DEXA. Quando os metodos foram comparados, nao se observaram diferencas significativas entre eles; alem disso, foram observadas correlacoes significativas entre os parâmetros comuns dos dois metodos (massa magra, massa gorda (kg) e massa gorda (%), r = 0,88 p < 0,05; r = 0,92 p < 0,05; r = 0,75 p < 0,05, respectivamente). Nossos dados sugerem que, para esta populacao especifica, a pletismografia pode ser utilizada como um metodo de avaliacao da composicao corporal.
Attitudes of nursing students facing questions related to alcohol, alcoholism and the alcoholic

Objective: To examine the attitudes of a sample of nursing students toward alcohol, alcoholism and the alcoholic. Methods: An exploratory study conducted with 144 students in their final year of undergraduate nursing in two private schools in the city of Ribeirão Preto SP. For data collection, we used the scale of attitudes towards alcohol, alcoholism and the alcoholic. Results: Attitudes toward alcohol were more negative than those that have been reported in the literature. The majority of participants considered the alcoholic to blame for his health problems and preferred not to work with this type of patient. Conclusion: The students’ attitudes to questions related to alcohol and alcoholism tended toward ambivalence and negativity, which can be attributed to lack of preparation received during their education. Despite recommendations made by specialists in the country, little has been invested in nursing education on alcohol and other drugs, especially in private schools.
Listing triangles in expected linear time on a class of power law graphs.

Enumerating triangles (3-cycles) in graphs is a kernel operation for social network analysis. For example, many community detection methods depend upon finding common neighbors of two related entities. We consider Cohen's simple and elegant solution for listing triangles: give each node a 'bucket. ' Place each edge into the bucket of its endpoint of lowest degree, breaking ties consistently. Each node then checks each pair of edges in its bucket, testing for the adjacency that would complete that triangle. Cohen presents an informal argument that his algorithm should run well on real graphs. We formalize this argument by providing an analysis for the expected running time on a class of random graphs, including power law graphs. We consider a rigorously defined method for generating a random simple graph, the erased configuration model (ECM). In the ECM each node draws a degree independently from a marginal degree distribution, endpoints pair randomly, and we erase self loops and multiedges. If the marginal degree distribution has a finite second moment, it follows immediately that Cohen's algorithm runs in expected linear time. Furthermore, it can still run in expected linear time even when the degree distribution has such a heavy tail that the second momentmore » is not finite. We prove that Cohen's algorithm runs in expected linear time when the marginal degree distribution has finite 4/3 moment and no vertex has degree larger than {radical}n. In fact we give the precise asymptotic value of the expected number of edge pairs per bucket. A finite 4/3 moment is required; if it is unbounded, then so is the number of pairs. The marginal degree distribution of a power law graph has bounded 4/3 moment when its exponent {alpha} is more than 7/3. Thus for this class of power law graphs, with degree at most {radical}n, Cohen's algorithm runs in expected linear time. This is precisely the value of {alpha} for which the clustering coefficient tends to zero asymptotically, and it is in the range that is relevant for the degree distribution of the World-Wide Web. « less
Petrography and diagenesis of Franciscan limestones

ABSTRACT Lithification of Franciscan limestones did not occur immediately after deposition as demonstrated by the preferred orientation of grains which is a result of compaction. Variable preservation of grains in adjacent layers of Laytonville Limestone are a result of variable degrees and different times of lithification; less compacted layers containing better preserved grains were lithified earlier than the more compacted layers. Recrystallization of the micrite followed burial and compaction of the limestone. All degrees of recrystallization are found in the coccoliths that originally composed at least 50 percent of the micrite. During advanced stages of recrystallization, coccoliths and other grains were transformed to a continuous and uniform calcite mosaic. At this stage the primary po osity of the sediment was removed and the sediment became completely lithified. Stylolites probably formed over a long period of time that started when the limestones were unlithified. Remnants of stylolites are found within the chert and stylolites are common at the margins of chert bodies. Most stylolites are younger than veins. Chert formed only in micritic limestones containing Radiolaria. The silica eventually replaced the original carbonate micrite between the radiolarian tests and the end result of this replacement was transformation of a limestone bed to chert.
Composição de lancheiras de alunos de escolas particulares de São Paulo

Objective: To evaluate the composition of lunchboxes of children attending second to fifth grades of private schools in Sao Paulo, Brazil. Methods: This cross-sectional study was performed in five units of a private school, located in different regions of the metropolitan area of Sao Paulo, Brazil. Every lunchbox was checked for three non-consecutive days in the year 2008. All children from second to fifth grades of these units (n=501) were studied and categorized according to the presence or absence of each food group in the lunchboxes on at least one of the three days of observation. Results: Among the children studied, 82% brought cereals, 67% artificial juices and other beverages, 65% milk and dairy foods, 51% cake, biscuits and cereal bars with fill ing and/or icing and 35% sausages in at least one day. The frequency of students who brought fruit and natural juices was 33%, and vegetables 4%. Girls more often took fruits and vegetables to school (p<0.05). Older students more often did not carry lunchboxes to the school, compared to younger ones, during the three days of observation (11 and 4% respectively; p<0,05). Conclusions: The composition of the school lunchboxes, despite some positive aspects, was inadequate. Lunchboxes presented over-processed foods, usually with a high content of sugar, fat and sodium, and absence of fruits and vegetables.
Low profile SIW slot antenna with wide beam-width radiation pattern

A linearly polarised antenna with wide beam-width is proposed. This antenna is based on substrate integrated waveguide (SIW) cavity. The half-power beam-width is about 145° in the E-plane, and 140° in the H-plane. This proposed antenna has a low profile of 0. 03λ 0 (λ 0 denotes to the space wavelength corresponding to the operating frequency centre) and a compact size of 0. 31λ 0 × 0. 31λ 0, which is very suitable for modern communication systems. The maximum gain is about 6 dBi, and the radiation efficiency is about 90% at the working frequency band. The cross polarisation is very small.
The effect of fault geometry and minimum shear wavespeed on 3D ground-motion simulations for an 6.5

We investigated the effects of fault geometry and assumed minimum shear wavespeed ( V S min ) on 3D ground-motion simulations (0 – 2.5 Hz) in general, using a moment magnitude ( M w ) 6.5 earthquake on the Hayward fault (HF). Simulations of large earthquakes on the northeast-dipping HF using the U.S. Geological Survey (USGS) 3D seismic model have shown intensity asymmetry with stronger shaking for the Great Valley Sequence east of the HF (hanging wall) relative to the Franciscan Complex to the west (footwall). We performed simulations with three fault geometries in both plane-layered (1D) and 3D models. Results show that the nonvertical fault geometries result in larger motions on the hanging wall relative to the vertical fault for the same Earth model with up to 50% amplifications in single-component peak ground velocity (PGV) within 10 km of the rupture. Near-fault motions on the footwall are reduced for the nonvertical faults, but less than they are increased on the hanging wall. Simulations assuming V S min values of 500 and 250 m = s reveal that PGVs are on average 25% higher west of the HF when using the lower V S min , with some locations amplified by a factor of 3. Increasing frequency content from 2.5 to 5 Hz increases PGV values. Spectral ratios of these two V S min cases show average amplifications of 2 – 4 (0.5 – 1.5 Hz) for the lower V S min west of the fault. Large differences (up to 2 ×) in PGVacross the HF from previous studies persist even for the case with a vertical fault or V S min of 250 m = s. We conclude that assuming a V S min of 500 m = s underestimates intensities west of the HF for frequencies above 0.5 Hz, and that low upper crustal (depth < 10 km) shear wavespeeds defined in the 3D model contribute most to higher intensities east of the
A review of High Dynamic Range Imaging on Static Scenes

A system for limiting the rotational speed of a turbocharger is disclosed. The turbocharger includes a compressor having an outlet fluidly coupled to an intake manifold of an internal combustion engine and a compressor outlet, a turbine having an inlet fluidly coupled to an exhaust manifold of the engine and an outlet. A control computer is configured to compute a maximum compressor outlet pressure value as a function of the compressor inlet pressure, the compressor inlet temperature, an operating condition other than the compressor inlet pressure or temperature and a maximum allowable turbocharger speed value, and to control a turbine swallowing capacity or efficiency control mechanism in a manner that limits compressor outlet pressure to the maximum compressor outlet pressure value to thereby limit rotational speed of the turbocharger to the maximum turbocharger speed value. The operating condition may be, for example, engine intake air flow rate or engine speed.
COMPARISON OF ESTIMATORS OF PARAMETERS FOR THE RAYLEIGH DISTRIBUTION

1 COMPARISON OF ESTIMATORS OF PARAMETERS FOR THE RAYLEIGH DISTRIBUTION Eldesoky E. Afify. Faculty of Eng. Shibeen El kom Menoufia Univ. Key word : Rayleigh distribution, least squares method, relative least squares, least absolute deviations, ridge regression, robust ridge regression, moment estimators, total deviations, mean squared errors, correlation coefficient. Abstract: This paper is concerned with estimation of parameters of the two parameter Rayleigh distribution. We use the least squares method (LS), relative least squares method (RELS.), least absolute deviation (LAD), ridge regression (RR) and robust ridge regression (RRR), moment (ME) and modified moment estimators (MME) for estimating the two parameter Rayleigh distribution. To compare between different methods of estimation, we use the total deviations (TD), mean squared error (MSE) and probability plot correlation coefficient (R). Numerical examples are worked out. Introduction Rayleigh distribution, which is a special case of Weibull distribution has wide application, such as, in life testing, Palovko (1978), in clinical studies dealing with cancer patients, Gross and Clark (1975) and Lee (1980). Ariyawansa and Templeton (1984) have also discussed some of its applications. Lalitha and Anand (1996) used the modified maximum likelihood to estimate the scale parameter of the Rayleigh distribution Cohen and Whitten (1982b) used the moment and modified moment estimators for the Weibull distribution, Samia and Mohamed (1993) used the moment and modified moment estimators for the Pareto distribution. Meintanis and Iliopoulos (2003) proposed a class of goodness of fit tests for the Rayleigh
IV. Some Memorable Scenes

In the remaining pages I shall offer some more detailed comments on a number of passages from both epics. Besides allowing slightly more attention to stylistic matters than was possible in the earlier chapters, this procedure also gives an opportunity to comment on some specific problems, and on a number of other approaches which have not been discussed so far. And Aphrodite, smiling goddess, herself took up a chair for Helen, and brought it and placed it in front of Alexandros [Paris]. There Helen, daughter of Zeus who wields the aegis, took her seat, turning her eyes aside, and spoke slightingly to her husband: ‘You came back from the fighting, then. I wish you had died there, brought down by a man of strength, who was once my husband. Oh, before now you used to boast that you were superior to the warrior Menelaus in strength and power of hand and spear. Well, go now, challenge the warrior Menelaus to fight you again face to face. But no, I would advise you to stop now, and not pit yourself against fair-haired Menelaus in warfare or combat without thinking - you might well be brought down by his spear. ’ Paris then answered her: ‘Wife, do not deride my courage with these hard taunts. This time Menelaus has beaten me with Athena’s aid, but another time I shall beat him: there are gods on our side too. No, come, let us enjoy the bed of love. Never before has desire so enveloped my heart, not even on that first time when I stole you away from lovely Lacedaimon and sailed off with you in my seafaring ships, and lay with you in love’s union in the island of Kranae - even that was less than the love and sweet desire for you that comes over me now. ’ So he spoke, and led the way to their bed: and his wife followed.

Experimental dust charging and dynamics with applications for planetary environments

Sickafoose, Amanda Anne (Ph.D., Astrophysical and Planetary Sciences) Experimental Dust Charging and Dynamics with Applications for Planetary Environments Thesis directed by Dr. Joshua E. Colwell There are many examples of dust dynamics near surfaces in the solar system, from particles observed levitating above the lunar horizon by the Surveyor spacecraft to the recently discovered dust ‘ponds’ on asteroid Eros. Such dust dynamics are most likely the result of interactions between charged dust particles and sheaths above planetary surfaces. This thesis presents an experimental investigation of dust charging and dynamics near surfaces with sheaths. The experiments are then related to planetary environments, with an emphasis on the Moon, Eros, and Mercury. The first set of experiments deals with the charging of isolated particles due to photoemission or exposure to a UV-induced photoelectron sheath. The charge on conducting particles is calculated using theoretical models and is consistent with measured values. The experiments also demonstrate that particle charge polarity changes from negative to positive with increasing distance from the photoemitting surface. Similar experiments with nonconducting particles reveal significant amounts of triboelectric potential (±15 V compared to ±1 to 2 V from the photoelectric processes), suggesting that this charging mechanism may be important on dusty planetary objects. In the second set of experiments, dust particles are levitated in a plasma sheath above a surface. The levitation heights, potentials, and charges of single particles as functions of the surface bias calculated from orbital-motion-limited theory agree well with the measured levitation heights and the dust potentials and charges obtained using force balance equations. When multiple dust particles are released from the surface, diffusion-like horizontal transport occurs in the plasma sheath over relatively short timescales (minutes). These experiments show that levitation and transport of dust above a surface with a plasma sheath occurs under a wide range of conditions. A brief investigation of the plasma environment of the spokes in Saturn’s rings finds that the experiments are not directly applicable to this system. However, the experimental results are employed to calculate sheath properties, levitated dust sizes, and particle levitation heights for the sunlit and nighttime hemispheres of the Moon, Eros, and Mercury. The experiments also imply that triboelectric charging may be the dominant charging process for dust on the surface of Mars.
