Simple Origami for Cub Scouts and Leaders
SIMPLE ORIGAMI FOR CUB SCOUTS AND LEADERS Sakiko Wehrman (408) 296-6376 [email protected] ORIGAMI means paper folding. Although it is best known by this Japanese name, the art of paper folding is found all over Asia. It is generally believed to have originated in China, where paper- making methods were first developed two thousand years ago. All you need is paper (and scissors, sometimes). You can use any kind of paper. Traditional origami patterns use square paper but there are some patterns using rectangular paper, paper strips, or even circle shaped paper. Typing paper works well for all these projects. Also try newspaper, gift-wrap paper, or magazine pages. You may even want to draw a design on the paper before folding it. If you want to buy origami paper, it is available at craft stores and stationary stores (or pick it up at Japan Town or China Town when you go there on a field trip). Teach the boys how to make a square piece from a rectangular sheet. Then they will soon figure out they can keep going, making smaller and smaller squares. Then they will be making small folded trees or cups! Standard origami paper sold at a store is 15cm x 15 cm (6”x6”) but they come as small as 4cm (1.5”) and as large as 24cm (almost 9.5”). They come in different colors either single sided or double sided. They also come in different patterns, varying from traditional Japanese patterns to sparkles. When you make an origami, take your time. -

The Security Printing Practices of Banknotes
The Security Printing Practices of Banknotes A Senior Project presented to the Faculty of the Graphic Communication California Polytechnic State University, San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Graphic Communication; e.g. Bachelor of Science by Corbin Nakamura March, 2010 © 2010 Corbin Nakamura Table of Contents Abstract 3 I - Introduction and Purpose of Study 4 II - Literature Review 7 III - Research Methods 22 IV - Results 28 V - Conclusions 34 2 Abstract Counterfeit goods continue to undermine the value of genuine artifacts. This also applies to counterfeit banknotes, a significant counterfeit problem in today’s rapidly growing world of technology. The following research explores anti-counterfeit printing methods for banknotes from various countries and evaluates which are the most effective for eliminating counterfeit. The research methods used in this study consists primarily of elite and specialized interviewing accompanied with content analysis. Three professionals currently involved in the security- printing industry were interviewed and provided the most current information about banknote security printing. Conclusions were reached that the most effective security printing methods for banknotes rest upon the use of layering features, specifically both overt and covert features. This also includes the use of a watermark, optical variable inks, and the intaglio printing process. It was also found that despite the plethora of anti-counterfeit methods, the reality is that counterfeit will never be eliminated. Unfortunately, counterfeit banknotes will remain apart of our world. The battle against counterfeit banknotes will have to incorporate new tactics, such as improving public education, creating effective law enforcement, and relieving extreme poverty so that counterfeit does not have to take place. -

Protection Coat for Banknotes

Like the famous Thaler coins, it travels from one hand to another, transforming in the process from a clean note to a wrinkled, dirty scrap of paper.

Design of Security Paper with Selective Frequency Reflection

Document leakage detection systems using security papers detect security papers using transceiving antenna gates. For the application of such systems, the structure must be designed with excellent reflection performance and stability at the angle of incidence. For this purpose, a loop and patch-type frequency selective structure based on a four-legged element structure was designed to have X-band frequency reflection characteristics. This design was based on optimized variables and was realized through the screen printing method using silver ink on A4 paper. It was verified that both the design and simulation results matched well. To verify its actual applicability, a detector module operable at 10 GHz was manufactured to observe both the security paper detection range in relation to distance with a signal strength of −10 dBm and the detection area in relation to the number of times that the security paper had been folded. -
Corrugated Board Structure: a Review M.C
ISSN: 2395-3594 IJAET International Journal of Application of Engineering and Technology Vol-2 No.-3 Corrugated Board Structure: A Review M.C. Kaushal1, V.K.Sirohiya2 and R.K.Rathore3 1 2 Assistant Prof. Mechanical Engineering Department, Gwalior Institute of Information Technology,Gwalior, Assistant Prof. Mechanical Engineering 3 Departments, Gwalior Engineering College, Gwalior, M. Tech students Maharanapratap College of Technology, Gwalior, [email protected] [email protected] [email protected] ABSTRACT Corrugated board is widely used in the packing industry. The main advantages are lightness, recyclability and low cost. This makes the material the best choice to produce containers devoted to the shipping of goods. Furthermore examples of structure design based on corrugated boards can be found in different fields. Structural analysis of paperboard components is a crucial topic in the design of containers. It is required to investigate their strength properties because they have to protect the goods contained from lateral crushing and compression loads due to stacking. However in this paper complete and detailed information are presented. Keywords: - corrugated boards, recyclability, compression loads. Smaller flutes offer printability advantages as well as I. INTRODUCTION structural advantages for retail packaging. Corrugated board is essentially a paper sandwich consisting of corrugated medium layered between inside II. HISTORY and outside linerboard.

Whether textured or smooth, pre- cious or disposable, these hardy amalgams of hydrogen-bonded fibers have changed the world many times over. For centuries, human history has been both literally written on the surface of paper and embedded deep within its structure. In folded and bound form, mats of cellulose fibers ushered in the Enlightenment; by enabling multiple iterations and revisions of an idea to span generations, they have facilitated the design of airships and skyscrapers, or the blueprints and calculations that made possible the first human footsteps on the moon. Generally speaking, we continue to recognize paper by a few basic characteristics: it is most often thin, portable, flexible, and readily ac- cepting of ink or inscription. There is, however, a particular sheet that is superlatively impressive, exhibiting an unintentional and unpreten- tious type of beauty. At first glance and in direct light, it may trick you into thinking it is merely ordinary paper; when backlit, the care- ful viewer may detect subtle hints of its historical pedigree via telltale watermarks or chain and laid lines. -
