Learning Complex Policy Distribution with CEM Guided Adversarial Hypernetwork
No full textCross-Entropy Method (CEM) is a gradient-free direct policy search method, which has greater stability and is insensitive to hyperparameter tuning. CEM bears similarity to population-based evolutionary methods, but, rather than using a population it uses a distribution over candidate solutions (policies in our case). Usually, a natural exponential family distribution such as multivariate Gaussian is used to parameterize the policy distribution. Using a multivariate Gaussian limits the quality of CEM policies as the search becomes confined to a less representative subspace. We address this drawback by using an adversarially-trained hypernetwork, enabling a richer and complex representation of the policy distribution. To achieve better training stability and faster convergence, we use a multivariate Gaussian CEM policy to guide our adversarial training process. Experiments demonstrate that our approach outperforms state-of-the-art CEM-based methods by 15.8% in terms of rewards while achieving faster convergence. Results also show that our approach is less sensitive to hyper-parameters than other deep-RL methods such as REINFORCE, DDPG and DQN.Interactive Intelligenc

Coilgun Structures
No full textResearch on coilguns at the Center for Electromechanics at the University of Texas at Austin (CEM-UT) has yielded considerable insight into the optimal design of coilgun structures. This research has indicated that the structural requirements are strong functions of launcher classification as well as acceleration mode. As a result, CEM-UT has built and tested the DC coaxial accelerator (DCA) coilgun, which is a multistage pulsed induction launcher that makes extensive use of composite material technology. The author presents analytical techniques (closed-form and numerical) used to make structural design calculations in the DCA launcher. The evolution of the multiturn wound DCA armature design is discussed. In addition, measured plastic deformation of this armature after a high-energy experiment is compared to that predicted by finite element analysisCenter for Electromechanic
The unlucky life story of Cem Sultan in Câm-ı Cem-âyîn and his new poems
No full textBu çalıĢmada, Bayatî‟nin Câm-ı Cem-âyîn adlı eserindeki Cem Sultan‟a
ait hasb-i hâl türü Ģiirler üzerinde durulmuĢtur. ÇalıĢmanın amacı eserden
yola çıkarak Ģairin hayatı, kiĢiliği, Ģiirleri ve dönemi hakkında bilinmeyenleri
ortaya koymaktır. ÇalıĢma, ġehzâde Cem (ö. 900/1495) ve Hasan Bayatî (ö.
900/1495‟te sağ) arasında Kâbe‟de Ģiirle baĢlayan dostluğu; Câm-ı Cem-âyîn
adlı eserin yazılıĢ sebebi, konusu, önemi ve neĢrini içermektedir. Bu
çalıĢmayla, Cem‟in Türkçe divanında yer almayan iki Ģiiri incelenmiĢ olup
hem bu Ģiirlerden hem de Ali Emîrî‟nin tespitlerinden yola çıkılarak Cem
Sultan‟a dair yeni bilgilere ulaĢılmıĢtır. Türk-Osmanlı neslinin öz tarihçesi
olan Câm-ı Cem-âyîn, Bayatî ve özellikle Cem Sultan‟ın hayat ve kiĢiliğine
dair önemli bilgiler içermesi bakımından oldukça önemli bir eserdir. ÇalıĢma
giriĢ, iki bölüm, sonuç ve kaynakçadan oluĢmaktadır. GiriĢ bölümünde, Câmı Cem-âyîn‟i eski harflerle neĢreden Ali Emîrî‟nin ön sözü ve eserin
dîbâcesindeki bilgiden hareketle eser ve müellifi hakkında bilgi verilmiĢ,
sonra adı geçen eserin Ģekil, içerik ve yayın bilgisi üzerinde durulmuĢtur.
Birinci bölümde, iki farklı eserden Cem‟in hayatına dair yeni bilgiler
aktarılmıĢ, Bayatî‟nin Farsça bir gazeli ve bu gazele Cem Sultan tarafından
yazılan Türkçe bir nazire gazel incelenmiĢtir. Ġkinci bölümde, Câm-ı Cemâyîn‟in hatime bölümünde yer alan ve çalıĢmamıza konu olan tarihî bir
“tahmisnâme” Ģekil, içerik, dil ve anlatım özellikleri yönünden incelenmiĢtir.
Hasb-i hâl türündeki bu önemli manzumenin tam metni, dil içi çevirisi ve
notlarla birlikte verildikten sonra sonuç ve kaynakça yazımıyla çalıĢma
tamamlanmıĢtır.This study focuses on Cem Sultan‟s poems written in the tone of friendly
chat included in the book Câm-ı Cem-âyîn by Bayatî. The study aims to
reveal what is unknown about the poet‟s life, personality, poems and his era.
This study is concerned with friendship between Prince Cem (date of death
900/1495) and Hasan Bayatî (date of death 900/1495 in life) which started in
Kaaba, the reason why the book “Câm-ı Cem-âyîn” was written, its
importance and publication. This current study analyses two poems of Cem
Sultan which are not included in his Turkish Collection of Poems, and makes
explorations about Cem Sultan by setting out from these two poems and from
the findings obtained by Ali Emîrî. Câm-ı Cem-âyîn, a short history of Ottoman Turks lineage, is a very important work in that it includes
information on Bayatî‟s and especially Cem Sultan‟s life and personality.
The study consists of introduction, two chapters, conclusion and a chapter
about bibliography. In the introduction part the preface written by Ali Emîrî,
information about the work based on the preface, and about the author is
presented and then information on the form, content and publication of the
book is offered. In Chapter One information about Cem Sultan‟s life is given
based on two different studies, and a lyric poem (gazal) written by Bayatî in
Persian language and a poem written by Cem Sultan in parallel to Bayatî‟s
gazal in Turkish language (nazire gazal) are also analysed in this chapter. In
Chapter Two a historical “tahmisnâme”, which is included in the epilogue of
Câm-ı Cem-âyîn and which is the subject matter of this study is analysed in
terms of form, content, and linguistic and stylistic properties. Having
paraphrased the full text of this important poem- which is in the tone of
friendly chat- with explanatory notes, the book reaches the conclusion and
ends with bibliography giving references

Does strict employment protection discourage job creation? Evidence from Croatia
No full textEmployment protection legislation in Croatia is among the most strict in Europe. Firing is difficult and costly, and flexible forms of employment are limited. Is this apparent rigidity reflected-as one would expect based on standard economic theory-in low labor market dynamics? Is job creation low and hiring limited? Is the job security of insiders achieved at the cost of outsiders not being able to enter thelabor market? The author attempts to answer these questions by examining job flows. If the employment protection legislation is binding, then job and worker turnover should be low. He shows that this is indeed the case. Hiring is limited and the average job tenure is very long in Croatia. Job destruction is low, however job creation is still lower. The result is accumulation of unemployment, in large part due to new labor market entrants not being able to find a job. The high degree of job protection also seems to strengthen the bargaining position of insiders and results in relatively high wages. So, wages in Croatia are higher than among its competitors, even after adjusting for productivity. These high labor costs are likely to contribute to limited job creation in existing firms, but also are likely to discourage the entry of-and thus job creation in-new firms. The author presents evidence that firm growth has been indeed limited in Croatia, contributing to the low employment level. The author examines other potential causes of high unemployment in Croatia (the unemployment benefit system, labor taxation, the wage structure, and skill and spatial mismatches). He argues that they do not play a substantial part in accounting for poor labor market outcomes in Croatia. The author concludes that the stringent employment protection legislation is the key labor market institution behind low job creation and high unemployment. Based on this he recommends specific measures aimed at liberalizing the labor market to foster job creation and employment.Labor Management and Relations,Labor Policies,Labor Markets,Environmental Economics&Policies,Trade Finance and Investment,Labor Markets,Labor Management and Relations,Labor Standards,Banks&Banking Reform,Environmental Economics&Policies
