description: We study a spin 1/2 fermion in a thick braneworld in the context of teleparallel $f(T, B)$ gravity. Here, $f(T,B)$ is such that $f_1(T,B)=T+k_1B^{n_1}$ and $f_2(T,B)=B+k_2T^{n_2}$, where $n_{1,2}$ and $k_{1,2}$ are parameters that control the influence of torsion and the boundary term. We assume Yukawa coupling, where one scalar field is coupled to a Dirac spinor field. We show how the $n_{1,2}$ and $k_{1,2}$ parameters control the width of the massless Kaluza-Klein mode, the breadth of non-normalized massive fermionic modes, and the properties of the analogue quantum-potential near the origin.

Fig. 8; Table 4
Diagnosis
Lentitornoceras gen. nov. reaching about 45 mm conch diameter. Extremely discoidal and involute adult stage (ww/dm ~ 0.25; umbilicus nearly closed at 30 mm dm); whorl profile strongly compressed (ww/ wh ~ 0.40); whorl expansion rate moderate (WER ~ 1.80). Flanks weakly convex, umbilical margin continuously rounded, venter very narrowly rounded. Ornament with lamellar, wide-standing biconvex growth lines.
Type material
Holotype GERMANY • Rhenish Mountains, Oberscheld; late Givetian (from a Red Ironstone block together with Pharciceras oberscheldense); Lotz 1901–1902 Coll.; illustrated in Fig. 8; MB.C.30413.
Etymology
After Hans Matern, to honour his studies on the ammonoids from the Dillenburg region.
Description
Only the holotype is available for description and illustration. It is a specimen of almost 30 mm diameter in iron-rich limestone, largely preserved with its shell (Fig. 8A). The shape is that of a flat lens; the ww/ dm ratio is less than 25%. The umbilicus is almost completely closed; it is bounded by a very shallow umbilical margin. The flanks are slightly convex and converge slightly to the very narrowly rounded venter. The shell bears widespread, lamellar-appearing growth lines, which are biconvex with distinct dorsolateral projection and higher ventrolateral projection across the flank; the ventral sinus is narrow and deep (Fig. 8C). The growth lines are coarser on the venter than on the flanks. The suture line is
typically tornoceratid with a wide, asymmetric adventive lobe, a narrow ventrolateral saddle and a small external lobe (Fig. 8B).
Remarks
Lentitornoceras materni gen. et sp. nov. can hardly be confused with another species from the red ironstone because of its peculiar conch morphology. Tornoceratids from other localities and stratigraphic horizons usually have a much more broadly arched venter. A comparable form is the late Givetian ‘ Lobotornoceras bensaidi ’ (Bockwinkel et al. 2013a); however, this form has a suture line with a very shallow adventive lobe.

description: We propose a method to study and constrain modified gravity theories for dark matter using CMB temperature anisotropies and polarization. We assume that the theories considered here have already passed the matter power-spectrum test of large-scale structure. With this requirement met, we show that a modified gravity theory can be specified by parametrizing the time evolution of its dark-matter density contrast, which is completely controlled by the dark matter stress history. We calculate how the stress history with a given parametrization affects the CMB observables, and a qualitative discussion of the physical effects involved is supplemented with numerical examples. It is found that, in general, alternative gravity theories can be efficiently constrained by the CMB temperature and polarization spectra. There exist, however, special cases where modified gravity cannot be distinguished from the CDM model even by using both CMB and matter power spectrum observations, nor can they be efficiently restricted by other observables in perturbed cosmologies. Our results show how the stress properties of dark matter, which determine the evolutions of both density perturbations and the gravitational potential, can be effectively investigated using just the general conservation equations and without assuming any specific theoretical gravitational theory within a wide class.

description: Within the framework of the German-Slovakian project to explore the Roman presence north of the Pannonian frontier on the Danube and the interaction with the native population beyond, the Germanic burial ground field in Sekule was examined. The site is located west of the Little Carpathians on the left side of the March. In four campaigns from 2012 to 2015, 36 burials from the later 1st century to the beginning of the 3rd century AD were studied. The majority of the dead were buried in the second half of the 2nd century AD. Almost all graves were equipped with Roman vessels made of bronze or ceramics. Together with the weapons in the men‘s tombs and the parts of the costume in the graves of the women, the connections between the Germanic population living in the lower Morava valley and the Roman Empire as well as far into the Germanic regions in the north are shown.

A name is proposed for the space. We work in the context of metric connections, or so called geometry with torsion, and describe the components of the torsion of the connection which imply certain equations of the G_2 structure. This article is devoted to finding the G_2-torsion tensors which classify our structure according to the theory in \cite{FerGray}.

description: We explore the coherent transfer of electronic signatures from a strongly correlated, optically gated nanoscale quantum dot to a weakly interacting, electrically backgated microscale channel. In this unique side-coupled `T' geometry for transport, we predict a novel mechanism for detecting Rabi oscillations induced in the dot through quantum, rather than electrostatic means. This detection shows up as a field-tunable split in the Fano lineshape arising due to interference between the dipole coupled dot states and the channel continuum. The split is further modified by the Coulomb interactions within the dot that influence the detuning of the Rabi oscillations. Furthermore, time-resolving the signal we see clear beats when the Rabi frequencies approach the intrinsic Bohr frequencies in the dot. Capturing these coupled dynamics, including memory effects and quantum interference in the channel and the many-body effects in the dot requires coupling a Fock-space master equation for the dot dynamics with the phase-coherent, non-Markovian time-dependent non-equilibrium Green's function (TDNEGF) transport formalism in the channel through a properly evaluated self-energy and a Coulomb integral. The strength of the interactions can further be modulated using a backgate that controls the degree of hybridization and charge polarization at the transistor surface.

description: A first systematic surface survey has been carried out in Rujum Saʿsaʿ, an ancient burial ground located south of the oasis of Tayma, increasingly threatened by infrastructural projects of the modern settlement. Within a 700 × 100 m large transect altogether 109 units, 101 of which are graves, were identified and recorded by Structure from Motion. There are three main types of structures: circular graves built of at least two rings of different height resulting in a stepped section; circular graves with cross-shaped interior; and rectangular graves attached to each other at the long side. The associated materials contained human bones, artifacts (primarily beads) and pottery. The latter is dominated by sherds covering most of the 2nd millennium BC. Less represented is Iron Age material (11th to 5th centuries BC). Only few sherds can be dated to the 3rd millennium BC.

description: Fieldwork in 2015/2016 (K. Bartl) The Neolithic site Mushash 163 in the western desert steppe (badia) of Jordan has been investigated since 2014 in cooperation with the Department of Antiquities of Jordan. During the excavations in the years 2015 and 2016, four round structures were recorded, which date back to the period between 8800 and 8400 cal BC, that is, the end of the Pre-Pottery Neolithic A (PPNA) (9800–8600 cal BC) and the Early Pre-Pottery Neolithic B (EPPNB) (8600–8300/8200 cal BC). This period, which has been documented rather little in the southern Levant, is of particular importance for the understanding of the process of neolithization, since it is associated with the beginning of domestication in the northern regions of West Asia. The work at the site of Mushash 163 aims to shed new light on this crucial period (of transition) in the southern Levant. The lithic material (D. Rokitta-Krumnow) The site of Mushash 163 is one of the very few Early Pre-Pottery Neolithic B settlements in the Jordanian desert steppe and is investigated since 2014. The main objective is the study of the stratigraphical-chrononological sequence and the structure of this 9th millennium BC site. By evaluating the lithic material, simplified production techniques could be demonstrated, which were applied mainly at household level. The manufacture of special types of tools, for which particular knowledge is required, is comparatively rare. However, the high number of borers in the tool kit indicates a certain specialization in the tool production at the site.

description: We investigate symmetric oscillators, and in particular their quantization, by employing semiclassical and quantum phase functions introduced in the context of Liouville-Green transformations of the Schrödinger equation. For anharmonic oscillators, first order semiclassical quantization is seldom accurate and the higher order expansions eventually break down given the asymptotic nature of the series. A quantum phase that allows in principle to retrieve the exact quantum mechanical quantization condition and wavefunctions is given along with an iterative scheme to compute it. The arbitrariness surrounding quantum phase functions is lifted by supplementing the phase with boundary conditions involving high order semiclassical expansions. This allows to extend the definition of oscillation numbers, that determine the quantization of the harmonic oscillator, to the anharmonic case. Several illustrations involving homogeneous as well as coupling constant dependant anharmonic oscillators are given.

description: Program SHELLSPEC is designed to calculate light curves, spectra, and images of interacting binaries and extra-solar planets immersed in a moving gaseous or dusty circumstellar matter. It solves simple radiative transfer along the line of sight in 3D moving media. The Roche model and synthetic spectra from the stellar atmosphere models such as TLUSTY from Ivan Hubeny can be used as a boundary condition for the radiative transfer. The latest publicly available version is Shellspec39. The code has been combined with other methods such as Doppler tomography and interferometry and used to analyze spectroscopic, photometric, and interferometric observations of binary stars and transiting exoplanets. A few examples are briefly mentioned.

We analyse the moduli space of classical vacua of the Bagger-Lambert theory corresponding to these Lie 3-algebras. We establish a one-to-one correspondence between one branch of the moduli space and compact riemannian symmetric spaces. We analyse the asymptotic behaviour of the moduli space and identify a large class of models with moduli branches exhibiting the desired N^{3/2} behaviour.

description: Coherent backscattering is due to constructive interferences of reciprocal paths and leads to an enhancement of the intensity of a multiply scattered field near its source. To observe this enhancement an array of receivers is conventionally placed close to the source. Our approach here is different. In a first experiment, we recover the coherent backscattering effect (CBE) within an array of sources and a distant receiver using time correlation of diffuse fields. The enhancement cone has an excellent spatial resolution. The dynamics of the enhancement factor is studied in a second experiment using correlation of thermal phonons at the same ultrasonic frequencies, without any active source.

description: The area in the south of Mt. Zion lies within the borders of the Protestant Cemetery. Two English pioneers, F. Bliss and A. Dickie, followed the course of the ancient city walls at the end of the 19th century by digging in subterranean tunnels and discovered that there are three walls above each other in this area. The most recently constructed one is from the first half of the 5th century. An older one with the same outline as the aforementioned is the one that Flavius Josephus refers to in Jewish Antiquities and the oldest one belongs to the Iron Age. This last wall might be a rare example of the wall that Hiskijahu built as he enlarged the city to create a protected space for the refugees from the northern Kingdom of Israel at the end of the 8th century BC. In addition to Bliss and Dickie, another excavation was begun in the same area by father B. Pixner in the 1980s. Y. Zelinger, who works for the IAA, then undertook a more focused excavation in an area near the cemetery that shows the continuation of the same city walls. His results allow a partial reconsideration of the findings in the cemetery. The GPIA started its work at this exceptional and unstudied site of ancient Jerusalem in 2015. In a first season, the old excavations were carefully cleaned and documented after more than 20 years of neglect. The work concentrated on the city walls as well as on the so-called “Essene Gate” which is also mentioned by Flavius Josephus. In 2016 the project was enlarged and three large new squares were opened. These squares are in the inside of the ancient city of Jerusalem; the aim of the project is to study the city’s settlement structures. After digging through banking structures from the Modern, Islamic and Medieval periods, the excavation has now reached the Byzantine level. Many promising loci have been documented that lead into the city extension built during the time of the influential empress Eudokia in the first half of the 5th century. The upcoming seasons are expected to reveal not only fascinating Byzantine structures but monumental Hasmonean/Herodian buildings. Since there are still three meters of cultural debris to the bedrock, also the traces of the Iron Age city can be awaited in that area. The GPIA’s Mt. Zion Excavation project offers the great and rare opportunity to research the history of Jerusalem in a huge and so far untouched area directly related to the old city walls.

description: We calculate the dynamics of a nanomechanical oscillator (NMO) coupled capacitively to a Cooper pair box (CPB), by solving a stochastic Schrodinger equation with two Lindblad operators. Both the NMO and the CPB are assumed dissipative, and the coupling is treated within the rotating wave approximation. We show numerically that, if the CPB decay time is smaller than the NMO decay time, the coupled NMO will lose energy faster, and the coupled CPB more slowly, than do the uncoupled NMO and CPB. The results show that the efficiency of energy loss by an NMO can be substantially increased if the NMO is coupled to a CPB.

description: Helium-burning hot subdwarf stars of spectral types O and B (sdO/B) are thought to be produced through various types of binary interaction. The helium-rich hot subdwarf star EC22536-5304 was recently found to be extremely enriched in lead. Here, we show that EC22536-5304 is a binary star with a metal-poor subdwarf F-type (sdF) companion. We have performed a detailed analysis of high-resolution SALT/HRS and VLT/UVES spectra, deriving metal abundances for the hot subdwarf, as well as atmospheric parameters for both components. Because we consider the contribution of the sdF star, the derived lead abundance for the sdOB, +6.3 +/- 0.3 dex relative to solar, is even higher than previously thought. We derive Teff = 6210 +/- 70 K, log g = 4.64 +/- 0.10, [Fe/H] = -1.95 +/- 0.04, and [$α$/Fe] = +0.40 +/- 0.04 for the sdF component. Radial velocity variations, although poorly sampled at present, indicate that the binary system has a long orbital period of about 457 days. This suggests that the system was likely formed through stable Roche lobe overflow (RLOF). A kinematic analysis shows that EC22536-5304 is on an eccentric orbit around the Galactic centre. This, as well as the low metallicity and strong alpha-enhancement of the sdF-type companion, indicate that EC22536-5304 is part of the Galactic halo or metal-weak thick disc. As the first long-period hot subdwarf binary below about [Fe/H] = -1, EC22536-5304 may help to constrain the RLOF mechanism for mass transfer from low-mass, low-metallicity red giant branch (RGB) stars to main-sequence companions.

description: We present the results of a deep near-infrared imaging survey of the Rosette Complex. We studied the distribution of young embedded sources using a variation of the Nearest Neighbor Method applied to a carefully selected sample of near-infrared excess (NIRX) stars which trace the latest episode of star formation in the complex. Our analysis confirmed the existence of seven clusters previously detected in the molecular cloud, and identified four more clusters across the complex. We determined that 60% of the young stars in the complex and 86% of the stars within the molecular cloud are contained in clusters, implying that the majority of stars in the Rosette formed in embedded clusters. We compare the sizes, infrared excess fractions and average extinction towards individual clusters to investigate their early evolution and expansion. We found that the average infrared excess fraction of clusters increases as a function of distance from NGC 2244, implying a temporal sequence of star formation across the complex. This sequence appears to be primordial, possibly resulting from the formation and evolution of the molecular cloud and not from the interaction with the HII region.

Evaluation of an alternate education program for students with behaviour problems
Creators: name: Reid, Sharon Lyn
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is a report of the first evaluation study of an alternate education program in the Surrey School District, province of British Columbia. Alternate programs are generally directed towards behaviour remediation, upgrading basic skills, and school reintegration for students suspended from regular classes. The Newton Junior Alternate Program (NJAP) was established with these goals in mind in 1978. The evaluation purpose was to provide NJAP staff with a complete systematic description of program operation — its antecedents, transactions and outcomes. This description is the basis for the set of recommendations prepared to aid future planning. The eclectic evaluation design developed for this study permitted a comparison between program intentions and actual occurrences. A descriptive matrix modelled after Stake (1967) was used as the framework for this comparison. To help formulate the evaluation questions, a general program description was prepared prior to the evaluation (February 1, 1981 to June 1, 1981). Several methods of data collection were used to avoid bias and error possible with single method approaches. The various sources of information and data were 22 students, three program staff members, 18 regular teachers, three administrators, and 12 parents. Qualitative and quantitative data were collected from above samples using semi-structured interviews, questionnaires, observation checklists, and achievement and attitude tests. The obtained information and data were summarized in terms of frequencies and percentages, and where appropriate, by means and standard deviations. With the exception of attendance, program goals were achieved for students who remained enrolled. However nine students were suspended. Ten students were reintegrated into regular classes at the end of the school year. Problems noted in the program maybe partially attributed to the fact that guidelines for student placement were not followed.

description: The emerging magneto-resistive RAM (MRAM) has considerable potential to become a universal memory technology because of its several advantages: unlimited endurance, lower read/write latency, ultralow-power operation, high-density, and CMOS compatibility, etc. This paper will demonstrate an effective technique to generate random numbers from energy-efficient consumer-off-the-shelf (COTS) MRAM chips. In the proposed scheme, the inherent (intrinsic/extrinsic process variation) stochastic switching behavior of magnetic tunnel junctions (MTJs) is exploited by manipulating the write latency of COTS MRAM chips. This is the first system-level experimental implementation of true random number generator (TRNG) using COTS toggle MRAM technology to the best of our knowledge. The experimental results and subsequent NIST SP-800-22 suite test reveal that the proposed latency-based TRNG is acceptably fast (~22 Mbit/s in the worst case) and robust over a wide range of operating conditions.

description: The rules governing cell division and differentiation are central to understanding the mechanisms of development, aging and cancer. By utilising inducible genetic labelling, recent studies have shown that the clonal population in transgenic mouse epidermis can be tracked in vivo. Drawing on these results, we explain how clonal fate data may be used to infer the rules of cell division and differentiation underlying the maintenance of adult murine tail-skin. We show that the rates of cell division and differentiation may be evaluated by considering the long-time and short-time clone fate data, and that the data is consistent with cells dividing independently rather than synchronously. Motivated by these findings, we consider a mechanism for cancer onset based closely on the model for normal adult skin. By analysing the expected changes to clonal fate in cancer emerging from a simple two-stage mutation, we propose that clonal fate data may provide a novel method for studying the earliest stages of the disease.

description: We initiate the study of cluster algebras in Feynman integrals in dimensional regularization. We provide evidence that four-point Feynman integrals with one off-shell leg are described by a $C_{2}$ cluster algebra, and we find cluster adjacency relations that restrict the allowed function space. By embedding $C_{2}$ inside the $A_3$ cluster algebra, we identify these adjacencies with the extended Steinmann relations for six-particle massless scattering. The cluster algebra connection we find restricts the functions space for vector boson or Higgs plus jet amplitudes, and for form factors recently considered in $\mathcal{N}=4$ super Yang-Mills. We explain general procedures for studying relationships between alphabets of generalized polylogarithmic functions and cluster algebras, and use them to provide various identifications of one-loop alphabets with cluster algebras. In particular, we show how one can obtain one-loop alphabets for five-particle scattering from a recently discussed dual conformal eight-particle alphabet related to the $G(4,8)$ cluster algebra.

description: We investigate the Euclidean path integral formulation of QCD at finite baryon density and temperature. We show that the partition function Z can be written as a difference between two sums Z+ and Z-, each of which defines a partition function with positive weights. We call the sign problem severe if the ratio Z-/Z+ is nonzero in the infinite volume limit. This occurs only if, and generically always if, the associated free energy densities F+ and F- are equal in this limit. We present strong evidence here that the sign problem is severe at almost all points in the phase diagram, with the exception of special cases like exactly zero chemical potential (ordinary QCD), which requires a particular order of limits. Part of our reasoning is based on the analyticity of free energy densities within their open phase regions. Finally, we describe a Monte Carlo technique to simulate finite-density QCD in regions where Z-/Z+ is small.

description: The south western edge of Transdanubia, in between the riverine alluvial landscape of the Danube and the first slopes of the Szekszárd hills, the happy coincidence of planned archaeological research projects (at Fajsz) and contract archaeological work prior to the building of the M6 motorway led to a large joint project, in cooperation of the Romano-Germanic Commission, Frankfurt, the Budapest Research Unit (Forschungsstelle) of the RGK and the Institute of Archaeology, RCH of the Hungarian Academy of Sciences. The region was a continuous scene for impacts from the onset of the Early Neolithic to the Copper Age, in the total of the 6th and 5th millennia cal BC. The evaluation involves several ongoing and already finalised MA and PhD programmes. The 4th year of our project made progress in the chronology of the late Neolithic Lengyel culture burials adjacent to the Alsónyék site; material analyses of the settlement pottery, the architecture of the Starčevo and the Lengyel settlements and a complex investigation of the chipped stone tools of the Alsónyék Lengyel settlement. The first volume on the environmental history of the Sárköz has also been completed.

description: Using data of five clusters of galaxies within the redshift range 0.15 $\leq$ z $\leq$ 0.25, imaged with the Nordic Optical Telescope (NOT) in the central $\approx$ 1 Mpc$^2$ in very good seeing conditions, we have performed an exhaustive inspection of their bright galaxy population. That range of redshift, where only a small amount of data with the required resolution and quality is available, is particularly important for the understanding of the formation and evolution of clusters of galaxies. We have inspected the color-magnitude relation (CMR) for those clusters and measured the blue fraction of galaxies in their cores to check for evidence of evolution as found in other works. Moreover, the visual classification of the galaxy morphology has been performed and the morphology-radius relation has been examined We have not found signs of evolution neither in the slope of the CMR nor in the blue fraction of galaxies. A diversity of situations regarding those parameters and in the morphological mixing has been noticed, with two out of five clusters containing a dominant late-type core population. The cluster A1878 stands out as some of its properties differ from those of the other clusters in the sample. No clear signs of evolution appear in our analysis. The data support the view that the morphology and the stellar content of the galaxies in our clusters have been already settled at z $\sim$ 0.2. Only the fraction of interacting galaxies in the clusters appear to be larger than in clusters like Coma although the number of clusters in the sample is small to give a definitive conclusion.

The structure of moral reasoning in hearing impaired students
Creators: name: Sam, Andrea Janice
Publisher: name: University of British Columbia

description: This study examined the structure of moral reasoning in the hearing impaired and its relationship with reading comprehension. Kohlberg's cognitive-developmental theory of moral development provided the conceptual framework for assessing the moral reasoning of fifteen subjects who ranged in age from twelve to fifteen years. These students, in a provincial school for the deaf, were not multiply handicapped and had an average hearing loss of greater than 100dB in the better ear. Four modified dilemmas from Kohlberg's Moral Judgment Instrument were administered to each subject in a separate interview. Each subject read a dilemma and were then shown a corresponding videotaped dilemma in American Sign Language (ASL). The interview which followed was videotaped and utilized each subject's preferred mode of communication. Analysis of the transcriptions from the videotapes indicated that the hearing impaired were reasoning at Stage 1 and Stage 2 while their hearing peers of similar age are reasoning at Stage 2, Stage 3 and Stage 4. The subjects' weighted average scores (for moral reasoning) were correlated with their Reading Comprehension (scaled) scores from school administered Stanford Achievement Tests for the Hearing Impaired and a significant positive correlation (r=.6161; p<.0l) was found. On the basis of these pilot findings it was suggested that moral reasoning may be related to language development. Implications of these findings were examined and areas for future research were suggested.

description: A consistency criterion for price impact functions in limit order markets is proposed that prohibits chain arbitrage exploitation. Both the bid-ask spread and the feedback of sequential market orders of the same kind onto both sides of the order book are essential to ensure consistency at the smallest time scale. All the stocks investigated in Paris Stock Exchange have consistent price impact functions.

description: The joint project including scientists from the Ukraine and Germany is devoted to settlement history of the 4th and 5th century AD in the modern district of Kharkiv. Currently the investigations are focused on a region in the vicinity of Voitenki. Surveys during the last two years completed the data base about settlements of the Chernyakhov culture and brought to light a number of unknown settlements along the river Sukhoy Merchik. Now considerations based on facts are possible for the prospected region concerning the density of settlement or the distances between the settlements. Furthermore, least cost paths analyses offer information about the infrastructure. The analyses of ceramics from Voitenki and ten other settlements provide insight into the infrastructure of the region as economic space. The Excellence Cluster TOPOI offered the possibility to use several natural scientific methods (MGR, pXRF, WD-XRF, thin sections) based on the archaeological evaluation of the wheel-thrown pottery. One of the main results is that in Voitenki and the other settlements pottery was largely produced locally. Only few examples indicate that vessels were removed from one settlement to another. As an important part of this project excavations were continued in Voitenki itself. In part B of this settlement the area between pottery kilns has been examined. On the corresponding cemetery previously more than 230 graves had been found.

description: The work of the Pergamon excavation in 2017 concentrated on the exploration of the Hellenistic residence city and its surroundings within the framework of the current research programme, whose field work could be completed. The focus was on geophysical prospections and stratigraphic trenches on the burial mound Yığma Tepe. To test hypotheses on the development of the settlement history of the city hill of Pergamon, Bau X on the western slope was examined. The survey of the Kane-peninsula was finished; it provided unexpected insights into the importance of the site for traffic and trade in the microregion. The extensive monument preservation measures at Pergamon concentrated on the Gymnasion and the Red Hall. A detailed preliminary report, which contains also information about other fields of activity such as the study of elite burial practises, will be published in “Archäologischer Anzeiger” 2018/2.
Data-Driven Optimized Tracking Control Heuristic for MIMO Structures: A Balance System Case Study

description: A data-driven computational heuristic is proposed to control MIMO systems without prior knowledge of their dynamics. The heuristic is illustrated on a two-input two-output balance system. It integrates a self-adjusting nonlinear threshold accepting heuristic with a neural network to compromise between the desired transient and steady state characteristics of the system while optimizing a dynamic cost function. The heuristic decides on the control gains of multiple interacting PID control loops. The neural network is trained upon optimizing a weighted-derivative like objective cost function. The performance of the developed mechanism is compared with another controller that employs a combined PID-Riccati approach. One of the salient features of the proposed control schemes is that they do not require prior knowledge of the system dynamics. However, they depend on a known region of stability for the control gains to be used as a search space by the optimization algorithm. The control mechanism is validated using different optimization criteria which address different design requirements.
