description: Στόχος της παρούσα εργασίας ήταν η παρουσίαση του μηχανισμού της αυτοκρατορικής γραμματείας του βυζαντινού κράτους και η περιγραφή της δομής και της λειτουργίας της. Εξετάσαμε τους αξιωματούχους που υπηρέτησαν σε αυτή και περιγράψαμε τα γραμματειακά τους καθήκοντα, τους τιμητικούς τίτλους που λάμβαναν, τη θέση που κατείχαν στην κρατική ιεραρχία, καθώς και τους υφισταμένους που βρίσκονταν στην υπηρεσία τους. Επιπλέον, παρουσιάσαμε τις αλλαγές που έλαβαν χώρα στην αυτοκρατορική γραμματεία από την πρώιμη στη μέση βυζαντινή περίοδο και την εξέλιξη των αξιωματούχων που είχαν γραμματειακά καθήκοντα, ορισμένοι από τους οποίους διατηρήθηκαν και στις δύο περιόδους, ενώ άλλοι έπαυσαν να λειτουργούν ή εξελίχθηκαν σε δικαστικούς λειτουργούς. Ασχοληθήκαμε επίσης με την δικαστική λειτουργία που ανέπτυξαν ορισμένα από τα μέλη της αυτοκρατορικής γραμματείας.
description: The aim of this study was the presentation of the mechanism of the imperial secretariat at the Byzantine state and the description of its structure and function. We examined the officials who served in this and we described their secretariat duties, the honorary titles they received, the position they held in the state hierarchy, as well as the subordinates who were in their service. Moreover, we presented the changes that took place in the imperial secretariat from the early to middle byzantine period and the evolution of the officials who had secretariat duties and it is worth mentioning that some of them were maintained in both periods, while others either ceased to perform their tasks or evolved to magistrates. We also worked on the judicial function some members of the imperial secretariat had developed.

description: OGLE-TR-132b transits a very metal-rich F dwarf about 2000 pc from the Sun, in the Galactic disc towards Carina. It orbits very close to its host star (a = 0.03 AU) and has an equilibrium temperature of nearly 2000 K. Using rapid-cadence transit photometry from the FORS2 camera on the VLT and SUSI2 on the NTT, and high-resolution spectroscopy with UVES on the VLT, we refine the shape of the transit light curve and the parameters of the system. In particular, we improve the planetary radius estimate, R=1.18 +- 0.07 R_J and provide very precise ephemeris, T_tr=2453142.59123 +- 0.0003 BJD and P=1.689868 +- 0.000003 days. The obtained planetary mass is 1.14 +- 0.12 M_J. Our results give a slightly smaller and lighter star, and bigger planet, than previous values. As the VLT/FORS2 light curve obtained in this analysis with the deconvolution photometry algorithm DECPHOT shows a transit depth in disagreement with the one obtained by a previous study using the same data, we analyze them with two other reduction methods (aperture and image subtraction). The light curves obtained with the three methods are in good agreement, though deconvolution-based photometry is significantly more precise. It appears from these results that the smaller transit depth obtained in the previous study was due to a normalisation problem inherent to the reduction procedure used.

description: The aim of the present master project was the study of the known data, both published and unpublished, concerning the holy martyrs and confessors of the Church of Cyprus during the first five centuries of christian era. Having stated as criteria of inclusion in our study, apart from the chronological, the geographical one (the martyrdom in Cyprus), after the necessary introduction -where analysis about the method followed in our project-, in Part A we have examined the known by the sources cases of saints, which are with certainty in accord to these presuppositions, creating at the same time the hagiographical dossier for each saint or group of saints. Furthemore, for the completion of a sphaerical examination of our subject, we have included correspondingly in three chapters (Part B, Part C and Appendix), in a more concise form, martyrs of Cyprus of doubtful period or proof, the known archaeological proofs about the honour of holy martyrs inland and, finally, not included in our study and wrongly concerned as martyrs of Cyprus. Our project ends by the relative conlusions, where the most important new material provided is underlined and summed up. Ending, it should be stressed that it is the first time that the subject under examination is being approached on a clearly scientific basis under the light of several primigenious sources.

We further conjecture that there is no universally optimal spherical code of 24 points in S^3, based on numerical computations suggesting that every 5-design consisting of 24 points in S^3 is in a 3-parameter family (which we describe explicitly, based on a construction due to Sali) of deformations of the D_4 root system.

Weighted Bures Length Uncovers Quantum State Sensitivity

Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The unitarity of quantum evolutions implies that the overlap between two initial states does not change in time. This property is commonly believed to explain the lack of state sensitivity in quantum theory, a feature that is prevailing in classical chaotic systems. However, a distance between two points in classical phase space is a completely different mathematical concept than an overlap distance between two points in Hilbert space. There is a possibility that state sensitivity in quantum theory can be uncovered with a help of some other metric. Here we show that the recently introduced Weighted Bures Length (WBL) achieves this task. In particular, we numerically study a cellular automaton-like unitary evolution of N qubits, known as Rule 54, and apply WBL to show that a single-qubit perturbation of a random initial state: (a) grows linearly in time under the nearest neighbour interaction on a cycle, (b) appears to grow exponentially in time under interaction given by a random bipartite graph.

description: The increasing needs for bandwidth worldwide, have led to the gradual development of optical access networks and more specifically to the development of passive optical networks. For this reason, the aim of the present thesis is to design and develop a simulator for the aforementioned passive optical networks (and in particular for the xg-pon networks), in order to implement: all the functions described in the standardization of the itu organization, and the sppt and swppt policies (downstream direction) and the ifaistos policy (upstream direction). In collaboration with the supervisor, omnet (version 4.6) was chosen as my simulation tool, which is an open-source, modular, object-oriented discrete-event simulation program with a very powerful graphical user interface. To sum up, in this thesis, at first there is an introduction to optical networks, mainly focusing on passive optical networks. Then the design principles of the simulator and the simulation environment are described. Finally, the experiments conducted using the simulator, their results (which are presented by diagrams) and some conclusions based on those leads, are analyzed.
The body of letters in Proust's Albertine Disparue
Creators: name: Springer, Frances Evelyn
Publisher: name: University of British Columbia

description: In this second to last volume of "A la recherche du temps perdu," Proust's hero turns from a busy world of receptions and grandes soirées to a more introspective, contemplative world of writing letters, which, in its way, is just as instructive to the aspiring writer as are the lessons he learned from stepping out into high society. The large body of letters in "Albertine disparue" offers Marcel the opportunity to experience at first hand how written language functions. In effect, language and how it generates meaning in Proustian terms is one of the central issues in the Albertine sequence. I study how this unique experience with a varied and substantial correspondence allows the hero to penetrate the mysteries of the written word. I proceed with a detailed examination of the various letters and telegrams, dividing them into different categories and determining how these letters fit into the storyline, i.e., how they relate to the structure of the narrative text. Subsequently, I examine how the interpretation of these letters informs the hero's understanding of language. "Albertine disparue" raises questions about the relationship of words and their meaning, and about writing and its ability to represent reality. Ultimately, Marcel responds to these questions as he learns how language signifies for him through his extensive personal experience with the written word in the large corpus of letters in "Albertine disparue."

description: The structure of real-world multilayer infrastructure systems usually exhibits anisotropy due to constraints of the embedding space. For example, geographical features like mountains, rivers and shores influence the architecture of critical infrastructure networks. Moreover, such spatial networks are often non-homogeneous but rather have a modular structure with dense connections within communities and sparse connections between neighboring communities. When the networks of the different layers are interdependent, local failures and attacks may propagate throughout the system. Here we study the robustness of spatial interdependent networks which are both anisotropic and heterogeneous. We also evaluate the effect of localized attacks having different geometrical shapes. We find that anisotropic networks are more robust against localized attacks and that anisotropic attacks, surprisingly, even on isotropic structures, are more effective than isotropic attacks.

Αρχικά, παρουσιάζεται μια λεπτομερή περιγραφή της τεχνολογίας RFID καθώς και των ασύρματων δικτύων αισθητήρων WSNs. Στην συνέχεια, γίνεται λόγος για την ενσωμάτωση της τεχνολογίας RFID στα δίκτυα αυτά (WSNs) και στο τέλος υλοποιείται ένας προσομοιωτής με σκοπό την μέτρηση της ενεργειακής κατανάλωσης των Pure και Slotted ALOHA πρωτοκόλλων και των παραλλαγών τους για την απόδοση της ενέργειας. Τα πειράματα υλοποιήθηκαν για καταστάσεις συγκρούσεων ( in collisions) και αδράνειας (in idle listening). Τα αποτελέσματα αυτών των πειραμάτων που έγιναν, έδειξαν ότι μετρώντας την κατανάλωση ενέργειας κατά την διάρκεια των συγκρούσεων, οι Slotted ALOHA παραλλαγές έχουν χαμηλότερη κατανάλωση ενέργειας (κυρίως η muting – earlyend) σε σχέση με τις Pure ALOHA. Επιπλέον, η κατανάλωση ενέργειας που προκλήθηκε κατά τα διαστήματα που ο αναγνώστης βρισκόταν σε κατάσταση αδράνειας είναι με μεγάλη διαφορά η μεγαλύτερη για τις slotted εκδόσεις χωρίς earlyend, ενώ παρατηρήθηκε ακόμη ότι σε ορισμένα πρωτόκολλα μετά από ένα διάστημα άρχιζε να πέφτει η κατανάλωση της ενέργειας τους λόγω της συχνής εμφάνισης συγκρούσεων στο σύστημα, με αποτέλεσμα να μειώνεται ο χρόνος που το σύστημα ήταν αδρανές.
description: The aim of the present thesis was the study of the energy efficiency of RFID anti - collisions protocols and their suitability for use in RFID systems embedded in wireless sensor networks WSNs. First of all, presents a detailed description of RFID technology and wireless sensor networks WSNs. Then, descripts about the integration of RFID technology in WSNs wireless sensor networks and finally implements a simulator to measure the energy consumption of Pure and Slotted ALOHA protocols and their variants for the energy efficency. The experiments were carried out for two situations of collision situation (in collisions) and idle (in idle listening). The results of these experiments have shown that Slotted ALOHA variants have lower energy consumption and is particularly characterized muting - earlyend relative to Pure ALOHA by measuring the power consumption during the collision. In addition, energy consumption caused by the time the reader was idle is by far the largest for slotted versions without earlyend, while still observed in some protocols that after a while began to fall the consumption of energy due the frequent occurrence of conflicts in the system, thereby reducing the time that the system was inactive.

description: Properties of the optical reference geometry related to Kerr-Newman black-hole and naked-singularity spacetimes are illustrated using embedding diagrams of their equatorial plane. Among all inertial forces defined in the framework of the optical geometry, just the centrifugal force plays a fundamental role in connection to the embedding diagrams because it changes sign at the turning points of the diagrams. The limits of embeddability are given, and it is established which of the photon circular orbits hosted the by Kerr-Newman spacetimes appear in the embeddable regions. Some typical embedding diagrams are constructed, and the Kerr-Newman backgrounds are classified according to the number of embeddable regions of the optical geometry as well as the number of their turning points. Embedding diagrams are closely related to the notion of the radius of gyration which is useful for analyzing fluid rotating in strong gravitational fields.

description: A theoretical formalism leading to elegant derivation of formulae for all spin observables is outlined for photo production of mesons with arbitrary spin parity $s^π$. The salient features of this formalism based on irreducible tensor techniques are i) the number of independent irreducible tensor amplitudes is $4(2s+1)$, ii) a single compact formula is sufficient to express these amplitudes in terms of allowed electric and magnetic multipole amplitudes and iii) all the spin observables including beam analyzing powers as well as the differential cross section are expressible in terms of bilinear irreducible tensors of rank 0 to $2(s+1)$. The relationship between the irreducible tensor amplitudes and the helicity amplitudes is elucidated in general and explicit expressions for the helicity amplitudes are given in terms of the irreducible tensor amplitudes in the particular cases of pseudoscalar and vector meson photo production. The connection between the irreducible tensor amplitudes introduced here and the well known CGLN amplitudes for photo production of pseudoscalar mesons is also established.

description: Motivated by the literature on opinion dynamics and evolutionary game theory, we propose a novel mathematical framework to model the intertwined coevolution of opinions and decision-making in a complex social system. In the proposed framework, the members of a social community update their opinions and revise their actions as they learn of others' opinions shared on a communication channel, and observe of others' actions through an influence channel; these interactions determine a two-layer network structure. We offer an application of the proposed framework by tailoring it to study the adoption of a novel social norm, demonstrating that the model is able to capture the emergence of several real-world collective phenomena such as paradigm shifts and unpopular norms. Through the establishment of analytical conditions and Monte Carlo numerical simulations, we shed light on the role of the coupling between opinion dynamics and decision-making, and of the network structure, in shaping the emergence of complex collective behavior in social systems.

Law-in-spacing : geographies of territorialization and resistance
Creators: name: Stewart, Lynn Alison
Publisher: name: University of British Columbia
Year: 2008

description: My thesis revolves around the extension of Anglo-American common law to the newly acquired territories of the Old Northwest and Louisiana. Both of these territories had French-speaking populations with traditions of European Civil law systems. I suggest that the extension of common law to these territories highlighted a process of law-in-spacing, a process by which the private law principles of common law became increasingly visible in the context of these traditionally Civil law populations. I also show that the common law had specific and unforeseen consequences for these French-speaking populations. I use concrete issues such as land and slavery to suggest that there are not only geographies of law, but geographies of custom. I also discuss the production of space as it relates to slavery.

description: We present a concept of a millimeter wavefront sensor that allows real-time sensing of the surface of a ground-based millimeter/submillimeter telescope. It is becoming important for ground-based millimeter/submillimeter astronomy to make telescopes larger with keeping their surface accurate. To establish `millimetric adaptive optics (MAO)' that instantaneously corrects the wavefront degradation induced by deformation of telescope optics, our wavefront sensor based on radio interferometry measures changes in excess path lengths from characteristic positions on the primary mirror surface to the focal plane. This plays a fundamental role in planned 50-m class submillimeter telescopes such as LST and AtLAST.

description: In a functional approach to QCD the infrared behaviour of Landau gauge Green functions is investigated. It can be proven that the ghost Dyson-Schwinger equation implies the Gribov-Zwanziger horizon condition. Its relation to the Kugo-Ojima confinement scenario is elucidated. Positivity violation for gluons is demonstrated, and the analytic structure of the gluon propagator is studied. Quark confinement is related to an infrared divergence of the quark-gluon vertex. It is shown that in the latter various components are non-vanishing due to the dynamical breaking of chiral symmetry. As a result an infrared finite running coupling in the Yang-Mills sector is derived whereas the running coupling related to the quark-gluon vertex is infrared divergent. In Coulomb gauge QCD already the one-gluon-exchange (over-)confines. This leads to a vanishing quark propagator, and thus quarks are confined. Nevertheless colour singlet quantities derived from the quark propagator are well-defined. Especially the expression for the quark condensate proves that chiral symmetry is dynamically broken. As expected the properties of mesons can be directly calculated whereas the mass of coloured diquarks diverges, and thus diquarks are confined. The latter nevertheless possess a well-defined size. In the third part the results obtained so far will be used to formulate a covariant Faddeev approach to nucleons. The resulting amplitudes describe the quark core of the nucleon. Besides the mass of this state also the electromagnetic form factors are calculated. The results for charge radii and magnetic moments as a function of the quark current mass provide some indication what the missing pion cloud may contribute to the nucleons' properties.

description: Automotive traffic scenes are complex due to the variety of possible scenarios, objects, and weather conditions that need to be handled. In contrast to more constrained environments, such as automated underground trains, automotive perception systems cannot be tailored to a narrow field of specific tasks but must handle an ever-changing environment with unforeseen events. As currently no single sensor is able to reliably perceive all relevant activity in the surroundings, sensor data fusion is applied to perceive as much information as possible. Data fusion of different sensors and sensor modalities on a low abstraction level enables the compensation of sensor weaknesses and misdetections among the sensors before the information-rich sensor data are compressed and thereby information is lost after a sensor-individual object detection. This paper develops a low-level sensor fusion network for 3D object detection, which fuses lidar, camera, and radar data. The fusion network is trained and evaluated on the nuScenes data set. On the test set, fusion of radar data increases the resulting AP (Average Precision) detection score by about 5.1% in comparison to the baseline lidar network. The radar sensor fusion proves especially beneficial in inclement conditions such as rain and night scenes. Fusing additional camera data contributes positively only in conjunction with the radar fusion, which shows that interdependencies of the sensors are important for the detection result. Additionally, the paper proposes a novel loss to handle the discontinuity of a simple yaw representation for object detection. Our updated loss increases the detection and orientation estimation performance for all sensor input configurations. The code for this research has been made available on GitHub.

description: Neutrino beams at from high-energy proton accelerators have been instrumental discovery tools in particle physics. Neutrino beams are derived from the decays of charged pi and K mesons, which in turn are created from proton beams striking thick nuclear targets. The precise selection and manipulation of the pi/K beam control the energy spectrum and type of neutrino beam. This article describes the physics of particle production in a target and manipulation of the particles to derive a neutrino beam, as well as numerous innovations achieved at past experimental facilities.

description: This paper presents novel reconfigurable architectures for reducing the latency of recurrent neural networks (RNNs) that are used for detecting gravitational waves. Gravitational interferometers such as the LIGO detectors capture cosmic events such as black hole mergers which happen at unknown times and of varying durations, producing time-series data. We have developed a new architecture capable of accelerating RNN inference for analyzing time-series data from LIGO detectors. This architecture is based on optimizing the initiation intervals (II) in a multi-layer LSTM (Long Short-Term Memory) network, by identifying appropriate reuse factors for each layer. A customizable template for this architecture has been designed, which enables the generation of low-latency FPGA designs with efficient resource utilization using high-level synthesis tools. The proposed approach has been evaluated based on two LSTM models, targeting a ZYNQ 7045 FPGA and a U250 FPGA. Experimental results show that with balanced II, the number of DSPs can be reduced up to 42% while achieving the same IIs. When compared to other FPGA-based LSTM designs, our design can achieve about 4.92 to 12.4 times lower latency.

description: Η δυσχερής οικονομική κατάσταση της χώρας μας αναγκάζει πολλές επιχειρήσεις να αναδιαμορφώσουν την λειτουργία τους. Πλέον οι ελληνικές επιχειρήσεις συνειδητοποιούν όλο και περισσότερο της σημασία της σωστής οργάνωσης και του εξορθολογισμού της αποθηκευτικής λειτουργίας. Η πολιτική διαχείρισης αποθεμάτων μπορεί να συνεισφέρει άμεσα στη μείωση του λειτουργικού τους κόστος όσο και στην αποφυγή άσκοπων επενδύσεων. Κάνοντας ακριβής εκτιμήσεις όσον αφορά την ζήτηση των προϊόντων τόσο σε βραχυπρόθεσμο, μεσοπρόθεσμο όσο και σε μακροπρόθεσμο ορίζοντα, μια επιχείρηση μπορεί να υπολογίσει όλες τις παραμέτρους που απαιτούνται για την σωστή διαχείριση των αποθεμάτων της. Εφόσον παράλληλα εφαρμοστούν κατάλληλες μέθοδοι πρόβλεψης της ζήτησης, μπορεί να επιτευχθεί περαιτέρω σημαντική μείωση του επιπέδου των αποθεμάτων ακόμη και με ταυτόχρονη αύξηση του επιπέδου διαθεσιμότητας. Τα οφέλη που θα αποκομιστούν είναι πολύ μεγαλύτερα από την προφανή μείωση του σχετικού κόστους. Πλέον οι επιχειρήσεις δεν θα επιβαρύνονται με επιπρόσθετες δαπάνες όπως η επέκταση αποθηκευτικών χώρων ή η κατασκευή νέων εγκαταστάσεων. Στην παρούσα διπλωματική εργασία μελετούνται ευρέως διαδεδομένα υποδείγματα διαχείρισης αποθεμάτων και προβλέψεων με απώτερο σκοπό να εφαρμοστούν στην εταιρία ΙΚΕΑ, σχεδιάζοντας και προτείνοντας παράλληλα ένα μοντέλο πρόβλεψης της σχετικής ζήτησης.
description: Our country's difficult financial situation is forcing many companies to reform their operation. Nowadays, Greek companies increasingly become aware of the importance of good organization and rationalization of the storage operation. The inventory management policy can contribute directly to reduce their operating costs and to avoid unnecessary investments. Making accurate estimates of the demand of products both in the short, medium and long term, a company can calculate all the parameters required for the proper management of stocks. If appropriate forecasting methods of demand are implemented alongside can further reduce stock levels significantly while, on the same time, the level of availability increase. The acquired benefits are far greater than the obvious reduction of the costs. Furthermore, businesses will not burden with additional costs such as the extension of warehouses or the construction of new facilities. In the present thesis are studied widely prevalent models of inventory and forecasts management with a view to be implemented on the IKEA company, by designing and proposing at the same time a provision model of the relevant demand.
Theatre Under the Stars : the Hilker years
Creators: name: Sutherland, Richard

description: For nearly a quarter-century, from 1940 through 1963, Vancouver’s Theatre Under the Stars (TUTS) mounted annual summer seasons of musical theatre in Malkin Bowl, a converted bandshell in Stanley Park. By the early 1950s, TUTS, now a fully-professional company, had become an enormous popular and financial success, attracting crowds of up to 25,000 per week. For various reasons, the company closed down in 1963, yet so ingrained in Vancouver's cultural fabric had TUTS become, that in 1980 an amateur organization re-appropriated the name for its own summer musical productions in Malkin Bowl. Despite its acknowledged importance in Canadian theatre history, very little research has been devoted to this remarkable company. The purpose of this study, therefore, is to document the early history of TUTS, in particular the years 1940 through 1949 when TUTS was directly funded by the Vancouver Board of Parks and Recreation and dominated by the colourful, if somewhat erratic, personality of its general manager, Gordon Hilker. Material for the thesis was obtained primarily through sources located at the City of Vancouver Archives, supplemented by newspaper clippings and by personal interviews. Archival matter included programs, handbills, photographs, and Park Board records, especially minute books and correspondence files. This study will examine the circumstances leading to the creation and subsequent development of TUTS as a civic enterprise. Although the work is designed to be comprehensive, certain topics receive special attention: the nature of the programming; the evolution and training of Canadian talent; the development of a professional company; political factionalism in the elected Park Board; and the relationship between Hilker and the Park Board which varied from mutual admiration to mutual loathing. Particularly analyzed are the pivotal events of 1949 that resulted in a complete change of ownership and management.

description: Using the language of theory space, i.e. moose models, we develop a unified framework for studying composite Higgs models at the LHC. This framework--denoted little M-theory--is conveniently described by a theoretically consistent three-site moose diagram which implements minimal flavor and isospin violation. By taking different limits of the couplings, one can interpolate between simple group-like and minimal moose-like models with and without T-parity. In this way, little M-theory reveals a large model space for composite Higgs theories. We argue that this framework is suitable as a starting point for a comprehensive study of composite Higgs scenarios. The rich collider phenomenology of this framework is briefly discussed.

On the failure of effective-field theory in predicting a spurious spontaneous ordering and phase transition of Ising nanoparticles, nanoislands, nanotubes and nanowires

description: The present work clarifies a failure of the effective-field theory in predicting a false spontaneous long-range order and phase transition of Ising nanoparticles, nanoislands, nanotubes and nanowires with either zero- or one-dimensional magnetic dimensionality. It is conjectured that the standard formulation of the effective-field theory due to Honmura and Kaneyoshi generally predicts for the Ising spin systems a spurious spontaneous long-range order with nonzero critical temperature regardless of their magnetic dimensionality whenever at least one Ising spin has coordination number greater than two. The failure of the effective-field theory is exemplified on a few paradigmatic exactly solved examples of zero- and one-dimensional Ising nanosystems: star, cube, decorated hexagon, star of David, branched chain, sawtooth chain, two-leg and hexagonal ladders. The presented exact solutions illustrate eligibility of a few rigorous analytical methods for exact treatment of the Ising nanosystems: exact enumeration, graph-theoretical approach, transfer-matrix method and decoration-iteration transformation. The paper also provides a substantial survey of the scientific literature, in which the effective-field theory led to a false prediction of the spontaneous long-range ordering and phase transition.

description: Rodrigo de Miguel et al 2007 J. Phys. A: Math. Theor. 40 5241-5260: A noisy vector channel operating under a strict complexity constraint at the receiver is introduced. According to this constraint, detected bits, obtained by performing hard decisions directly on the channel's matched filter output, must be the same as the transmitted binary inputs. An asymptotic analysis is carried out using mathematical tools imported from the study of neural networks, and it is shown that, under a bounded noise assumption, such complexity-constrained channel exhibits a non-trivial Shannon-theoretic capacity. It is found that performance relies on rigorous interference-based multiuser cooperation at the transmitter and that this cooperation is best served when all transmitters use the same amplitude.

description: Production planning is an activity that precedes production and is related to production strategy. A better demand forecast has as a result a better production planning. The purpose of this paper is to show how production planning, supplies of raw materials and the level of stocks are affected, on the basis of demand forecasts in a production unit. Firstly, reference is made to the concept of supply chain with consequent reference to the company and the product. Demand forecasts are made by the methods of single exponential smoothing and moving average. In addition comparison is made between the actual and the optimal production. The results are aligned with the regular demand lots and the safety stock is calculated. Finally, the data and the conclusions reached are presented.
