We prove that every regular language is recognized by a deterministic two-way finite automaton whose control unit is strictly locally testing. Similarly, every picture language which can be described by a regular language can actually be described by a strictly locally testable language; this strengthens a result of Friedhelra Hinz.

Perwakilan kod rantai ialah salah satu daripada Bahasa Penghuraian Gambar yang digunakan untuk mewakili garisan. Kertas kerja ini menfokuskan kepada terjemahan lukisan garisan dengan menerapkan algoritma kod rantaai dalam mendapatkan dua entiti geometri, iaitu simpang–T dan kawasan, bagi lakaran lukisan garisan dua dimensi. Algoritma kod rantai tertutup ini mengandaikan bahawa lakaran mewakili objek padu tiga dimensi. Algoritma ini ialah berasaskan kod rantai Freeman 8–kaitan dalam tetingkap 3×3. Terdapat dua faktor yang menentukan kejayaan algoritma ini. Pertama ialah arah penjelajahan sama ada ikut jam atau lawan jam. Kedua ialah lokasi permulaan bagi penjelajahan dalam tetingkap 3×3 tersebut. Kertas kerja ini menerangkan faktor-faktor ini dan aplikasi mereka dalam mendapatkan entiti geometri tersebut. Perbincangan ini dibantu oleh contoh lakaran objek blok–L untuk memudahkan pemahaman terhadap algoritma. Kertas kerja ini diakhiri dengan kesimpulan dan cadangan pembaikan. Kata kunci: Terjemahan lukisan garisan, kod rantaian, objek blok-L, Bahasa Penghuraian Gambar Chain code scheme is one of the Picture Description Languages used to represent lines. This paper focuses on the line drawing interpretation by utilising closed loop chain code algorithm as a tool in deriving two geometric entities, i.e. T–junction and region, of a two–dimensional line drawing sketch. The closed loop chain code algorithm assumes that the sketch represents a three–dimensional solid object. The algorithm is based on 8–connected 3×3 windows of Freeman chain code. Two factors determine the success of the algorithm. The first factor is the direction of traverses either clockwise or anti–clockwise. The other is the start location of the 3×3 window traverse. This paper explains these factors and their applications in deriving the geometric entities. The discussion is supported with an example of L–block object for clarification in the presentation of the algorithm. This paper is concluded with conclusion and future works. Keywords: Line drawing interpretation, chain code, L-block object, Picture Description Languages

This exploratory study examined the impact of implicit and explicit oral corrective feedback (CF) on the development of implicit and explicit knowledge of Japanese locative particles (activity de, movement ni and location ni) for those who directly received CF and those who observed CF in the classroom. Thirty-six college students in a beginning Japanese language course received either recast (implicit), metalinguistic (explicit) or no feedback during an information-gap picture description activity, and completed a timed picture description test (implicit knowledge) and an untimed grammaticality judgement test (explicit knowledge) in a pre-test, immediate post-test and delayed post-test. The results showed that overall there was no significant difference between CF types, and that CF benefited direct and indirect recipients similarly. Potential factors that might influence the effectiveness of CF, such as instructional settings, complexity of target structures and pedagogy styles, are discussed.

Ghostscript has a long history in the open source community and was developed at the same time that page description languages were evolving to the complex specification of PDF today. Color is a key component in this specification and its description and proper implementation is as complex as any other part of the specification. In this document, the color processing and management that takes place in Ghostscript is reviewed with a focus on how its design achieves computational efficiency while providing flexibility for the developer and user.
